I put a Strange S60 in my car and shortly thereafter took my car in for a rebuild of my 200R4. Art Carr told me my custom driveshaft (42") is about an inch too short and was barely catching the bushing in the transmission. Based on my numbers below the shop is right as I found my length should be 43 1/8".

There is very little data about exactly driveshaft lengths on the internet but I spent about 30min of research today and here are the numbers I've arrived at:

3rd gen Firebird 84-92 with 700R4 and stock rear end:
41.5"
3rd gen Firebird with 700R4 and Strange S60
40 1/8" (I called Strange to get this)

TTA with 200R4 and stock rear end:
44.5" (I added 3" because the 200R4 tail is 3" shorter than the 700R4)
TTA with 200R4 and Strange S60
43 1/8" (I'm subtracting 1 and 3/8" for the S60 swap. I got this from the 700R4 differences)

Can someone confirm the stock TTA driveshaft length for me? I've already thrown mine away!
Hopefully this should help out anyone in the future doing a driveshaft swap.
 
Mine is on my garage floor right now. Just the ds is 46 3/4" and the ds plus the yoke is 51 1/2"
