1970 442 cutlass driveshaft question

I am restoring a 1970 Cutlass convertible. I have a question about the driveshaft. The car was originally a 350 engine and 350 Turbo tranny. I upgraded to a 455 with 400 tranny. My question is, I have the original 350 turbo driveshaft. Will this fit the 400 tranny setup? Are the Yolk splines the same? Is the driveshaft length the same? Will it fit as is??? Please help!

The driveshaft and yoke are both different from the TH350 original setup, I have an original TH400 driveshaft with correct yoke from a 1970 442, PM me if interested, thanks.
