Drag Racing Tech - TH400 driveshaft. how much longer?

going to a th400. how much longer does the DS need to be to fit properly? thanks. i wish the search worked right :(

mine was shorter...may be able to use a longer yoke. I have a long tailshaft th-400 though

hmmm ok. anyone recently do this and have a measurement?

No to hijack your thread. But I have a 3.50" driveshaft that I took out of my Firebird that has a t400 and Moser 12bolt that I'll sell cheap. Has 1350 ujoints front and back. $200 shipped. If you want to cut yours, let me know and I'll measure this one for you. It has the correct amount of yoke slip, etc and comes with a t400 yoke.

I have one at home for a th400 and 12 bolt setup I can measure if you need it, it was in a car already so I know it's the right lenth.
