I looked at 3 cars..2 big block 4 speeds and a smallblock 4 speed. All were about 49 1/2. That measurement is fron center of u-joints. I think there might be a 1/4-1/12" between big and small blocks ?

Thanks to all of you for measuring your driveshafts.......
I looked in RICK's Camaro Parts catalog. They show one driveshaft for all but T-400.......and another for T-400.
So I called RICKS and found out the Muncie,T-350 & Powerglide shaft is 49 1/2" and the T-400 shaft is 48 1/2".
I still need to have my friend who is keeping car for me, confirm Center-Center(U-Joint)measurement of my existing driveshaft....I regret now not getting this fact known, before I asked ya'all for your comparisons.....
Guess I'll post again after I hear what I'm dealing with for length.......as I've been told that my D.S. is short and I cant imagine WHY????

Chuck, your driveshaft measures 48 1/2" ctr to ctr of u joints. The 400 turbo driveshaft on my 71 Z measures the same. The machined surface which inserts into tranny, is exposed 1 1/2" on my car. Yours is exposed about 2 3/4". There is no side to side play in mine, when I check yours it moves about 1/8". I am answering your questions here in hopes someone may have answers for you. It may be ok the way it is, I just didn't think there should be any play in it.

I would think side to side play would definitely be bad!

To everyone thats trying to help me, THANKYOU!!!!!!
The 48.50 Center to Center(U-Joint)driveshaft is what I've learned to be correct for 69 Turbo 400 applications. I had no idea 2nd Gen Camaro used same.......
The only component changed in my cars drivetrain during its "renovation" was installing the attached pictured 12 Bolt.
It having U-BOLT pinion flange I'm told is wrong....This morning I received a Email, saying MANY different yokes were/are available. If we can narrow the yoke down to causing the "short" problem, who or where can I find out about a LONGER "correct" yoke??????????
Thanks so much, Chuck
