    1967 Mustang T-5 w/ 9" driveshaft length

    Just a heads up to anyone doing a small block/ T-5 / 9 inch combo.  I've seen some say a 51" driveshaft is the correct length.  After trying several driveshafts belonging to both myself and friends of mine I had to have an Explorer aluminum driveshaft shortened to 49". That's with about 3/4" play at the transmission.  Everything is in the stock location and the 9" is from a 1968 cougar.  While the center section of the 9" is not original to the rearend it doesn't look like the pinion yoke is different than other mustang centers I've seen.  I hope this helps anyone out ther doing this swap who may have been questioning their driveshaft measurement. Measurement was taken from center of yoke to center of yoke.

    How are you measuring your driveshafts? Centerline to centerline on the U joint yokes?

    Sorry, meant to say measured from center of the u-joint to center of u-joint. The middle of the cups.

    Re: 1967 Mustang T-5 w/ 9" driveshaft length

    I just put a new driveshaft on my 70 tonight, I had it built 50 1/4 inches center to center ofthe cap and it fit perfectly, there are two different pinion yokes that I know of with about 1.5 inches difference in length, not positive on the difference but it is noticeable. 

    The amount of fun is directly proportionate to the damage done.

    The Ford 9" pinion snout came in more than one length.
