You could just leave it and run it as is too. Most people in the drifting world don't even run the top half of the transmission bolts on their car in the event that they need to do a trans swap at the track. If you think about the size and quantity of the fasteners, it's overkill for how much clamping force there is holding it to the engine with all of the bolts in place.

I’ve thought about this as there are 9 other bolts that hold it on. This is one of the large bolts at 9 and 3 o’clock on the trans. Would it be bad to not run one of these in particular? It would make like a lot easier if I didn’t need to worry about it. This car will be mainly street driven and a little bit of auto x at most so nothing that would put a significant amount of stress on it.

Earls right, you dont need to really worry about it.
If I really wanted it out, I would use some really small drill bits (#50 to #10 or so) and drill a hole or two between the easy-out and the trans wall. You started doing this but 1/4" is way too big. Then drill a hole from the back side(mated to block side) as you have already done but further until you hit the easy-out. then get a small punch and hit the easy-out from that same direction opposite from which you inserted it. Now you should have a hole, continue to step up your drill sizes until you are almost touching the threads on the housing. Use a torch and heat the area, use an easy-out and try again.
I've been there more times than I can count. Good luck!

Well this is good to know. I think I might avoid it for the time being so I can focus my efforts on other parts of the car.
Thank you for the heads up.

your pilot hole in the back of the bolt is a pretty good size. what about just putting a big lag bolt in there (or tapping threads and putting a normal bolt in) and using a impact wrench on it? because it's from the back side, and will bottom out, a tightening rotation will loosen it. you risk snapping that bolt too, but its a bigger size than the easy-out so should take more torque.

Also a good idea. I feel like its so close to coming out you should just get it out of there.

This could be worth the try as I am mainly waiting at parts for the moment.
Wanted to test fit the headers so I could see if there would need to be any drilling done. Looks like just a couple of the corner holes might need to be widened. But much better than I had anticipated after what I had heard and read about these headers. I love how the white came out, really think it's gonna stand out nice in the calypso bay.

Top side:
Side mated to block:
Really confused about what's happening here. There's no threads there, so there's no point in trying to spin it. Find a suitable punch, heat the crap out of the area, hose it down with penetrant while it's hot, and smack it out with a 3 pounder. Just don't hit it hard enough to break the casting.
Spraying it with penetrant while it's hot should help suck the oil into the gap as the parts cool. That's the theory at least...
The only thing holding it in is corrosion. The easy-out could also be part of the problem if it's trying to expand the bolt out into the hole, so drilling small holes around that may help...

the point of spinning it is to utilize the impact gun, since it can hit alot harder/more times than the BFH.
can anyone with an engineering background surmise if either the rotational force or a directional force would be more effective?

Eh, given the scenario it takes way more work to attempt to spin it when compared to how easy it is punch it out.
Beyond that I would think you start getting into grain structure. @snap may have some more thoughts on that though.
That's a steel bolt into aluminum, and aluminum expands at a much lower temp so it should be fairly easy to get out with some heat, a punch, and a good hammer.
Edit: aluminum vs steel expansion (linear) is actually a 2:1 ratio. Neat
Send it flying across the garage! -

Send it flying across the garage!Believe me, heating it with a torch and hitting it with a hammer was my first train of thought. Did not get the results I was looking for. One of the start bolts that go through the trans housing had to be cut as well, came out very easily when I went to hit it with a punch and hammer.

Black interior has really come together nicely. For how little I have spent on it, I am really happy with how it has turned out. Contrast between the carpets and the seats isn't nearly as dramatic in person. Will run the tan sport seats for now, but will be looking to pick up an after market option during the winter.
How the car currently sits.
It's amazing how much time and work I've put into it, but from this angle it looks just like it did the day I picked it up minus it being lower. Starting to get really close for the motor to go in. I am waiting on parts right now before that can happen. Replacement brake line for the one I cut and some gaskets for the engine and transmission covering plate.
Kind of running out of stuff to do in the mean time, but I am hoping to get the parts I have for the transmission installed this weekend. Was gonna wait, but maybe start taking off and painting some of the trim pieces?
The trunk is what I should really figure out. I really don't know what to do for fixing that.

Place the transmission bell housing down with only a small gap in support under where the bolt is then it won't crack when hammering. Heat is key, if you heat that up it will come right out. If you only have a propane torch be patient, it will take a while to get the area sufficiently hot.

I did try with a torch, but maybe I need to keep the heat on it longer.

Keep in mind you are trying to heat a very large piece of aluminum, which is a great conductor of heat. It will spread the heat throughout the entire piece so you may need to hold the torch to it for quite a while to have an effect.

By awhile, he means a minimum of 5 minutes. You should see the casting start to glow and hold color in the grains. Also, Mapp gas is hotter than propane if you arent already using Mapp..

Oh shit, didn't know it needed to be that much. I'll have to grab another propane tank on the way home.

So I probably need a bigger torch. I was heating the area of the reaming stud for a good 5 minutes, the entire trans was warm to the touch, but no dice on getting it out. Tried two different punch sizes on both ends, used penetrating fluid while it was hot. Maybe I just need to cycle it more with the heat and fluid. Or need to utilize a friends bigger torch.
I replaced the selector shaft seal as well as the input shaft seal on the trans. Also did the carrier rod(what ever the thing is that the shifter sits in) bushing where it meets the trans as well as the shifter bearing. Need to rent a three prong puller for the output shaft.
I found the problem with my trunk. The lever in the picture below was getting stuck on the housing of the latch housing. I believe this is because the spring that this lever is on is not as taught and giving it some play. The lever would catch the side of the housing and not allow the latch to open. So for the time being, I have shaved the portion of the housing to make sure that it would not get caught. The picture below shows the lever pushed as far over, you can see how it would over lap.
My plan is to go to the junk yard on Saturday and find a new male trunk latch(the part that was stuck in the latching mechanism that I cut off to get the latching mechanism out of the car) and possible a new latching mechanism all together to see if it is in better shape. The lock itself I believe is completely toast. I'm pretty sure it's supposed to spring out when it's pushed in but it just says. So I might just buy a new one off eBay with a key as my last lock rebuilding experience did not go to plan.
