Default Stock Length Driveshaft for TH 350/400 Swap??

As in the title, will the stock length driveshaft work if I swap to TH350 or 400? I have a Strange c/m that is sweet and I would hate to have to sell it and buy another.

Also, I am using a Yank torque arm relo cross member. If I go to a TH 350 or 400, will I need a different cross member?

Thank you in advance,

You'll have to ask Yank about the crossmember. If you go with a TH400, you'll need a longer driveshaft. You can use a stock length DS with a long tail TH350

If youre using the Yank crossmember for an Auto car, then it will not work. If you are using the Yank crossmember for an M6 car, then it will work. You will just have to space the TH400 up one inch. I did this using a 6" length of 1"x1" square tube, bolting it between my tranny mount and the tranny. You will also need to get 1" longer bolts to attach the mount and spacer to the tranny. If you need a pic, let me know. Z28' is correct. You will need a longer DS with a TH400. The tranny is about 1.25" shorter to the end of the output shaft, and some slip yokes are shorter on a TH400 as well. So, the best thing to do is to measure when it is all in and get the proper size made.
