I just scored a rebuilt TH350 for $125. THe guys wife got pregnate, so yea...That's how it works for some.

Anyways, I looked around for a 82-84 44" driveshaft, but to no avail. Can I just swap the tail shaft off my 700r4 onto the TH350, and use my 94 Camaro V6 alluminum drive shaft with my 10bolt rear?

 

no, the output shafts are different, and so are the tail housings.
the only thing the same is the spline count and the seal and bushing.
you would have to completely disassemble both trannys to get the shafts out anyway...but no, they won't interchange

 

read this thread in the last post the guy used a 700 tail shaft on his th350 https://www.thirdgen.org/forums/tran...n-not-faq.html

 

Well, then what do I have to have to swap to a th350?? Forgive me for not searching, but I am a little drunk and I aint feeling like serching.

 

if you read carefully, he said tailshaft HOUSING.

which was actually NOT a long tail, because those are about 12" long and your 700 is about 6.
I really am not sure what he is talking about, except for the housing. the SHAFTS are different. which is what you said-- tailSHAFT.

I was answering your question.

I, personally have not tried to swap the housings, but I suppose it would work, the o-rings are the same, the bushings are the same and the driveshaft yokes are the same, I suppose if the housings are the same length then it would work. I don't currently have any short tail 350's around to check if the 700 housing fits, but when I get one, I will check.

 

actully if camaro kid has a longtail th350 the driveshaft from the 700r4 will fit and for the ta mount get the b&m or hurst kit for a th350 and bolt it in. if short shaft get the ta kit and have a driveshaft built or get one from a 200 trans
