Alright i gotta retap the threads on my tranny case for the rear tranny mount near the diff... the bolts keep pulling out of it, the threads are really messed up, so instead of a 10mm 1.25 thread im gonna go 12mm 1.25 thread... Does anybody have tips on tapping out the tranny case so i dont mess it up?

Find a tap drill chart and drill it to the correct size for that tap. Its aluminum, so if the hole is a bit small (a few thousandths) it will be ok. use lots of oil, go one turn in then a half turn out, start the tap straight, thats all I can think of

Have you conisered the line of products by heli-coil (thread repair kits) I have seen them hold 25 pounds without a problem in a medium size.

There are a wide variety of binary form setting solutions available to you, thread sealers for the repair of the binding of the helicoil insert and the hole that has just been freshly chased with the tap. I wouldn't see the harm in throwing a thin layer of jb-weld or other epoxies of lateral strength when you perform the operation.

I would not recommend running out and buying a tap & die set just for one hole. Granted they are great to have around but the cheap sets suck ***, you get a name brand set and it will have the quality but the quantity of pieces will be low for a budget minded purchase.

I chime in here and there to rescue a thread... usually when I'm searching the site for info I decide to contribute a little bit.

gotta agree with the heli-coil

ever do anything with a porsche 911 and a small block?

I left arkansas and moved back to florida, sadly I have no room and to many cars here to take on that project. It has been months and months since I've touched a v8. I have kept an eye open for a 73-74 porsche for some time but they aren't that plentifull in a restoration-needed state (meaning complete and affordable) - most people that are selling them have kept the cars well maintaned and want an arm/leg for it. The biggest problem I have is that all my tools got left behind (along with my dog) and I am borrowing ---- to just get by with what I'm working with now (variety of imports, mercedes diesel, and a special corolla project). About to buy an ac/dc TIG machine so maybe I can break out the welding mask once again and make some stainless manifolds and aluminum goodies. I figure I might find the right car by the time that the ultra megasquirt project is complete.

Eventually I will get around to moving back out to the mountains and then I will have a place&time to frame-off a 911, until then I will keep searching for the right deal - hope I don't stray off and buy another crx to toy with.
