Driveshaft/yoke?

[xRaCeR69]

how far should the yoke stick out of tranny on a ump modified with 4 bar rear suspension,and a bert tranny, The yoke I have is 7 1/2" from the center of the u joint to the end of it with approx. 5 3/4" that could slide on to the tranny. trying to figure out driveshaft length. Thanks

I know on a late model 2 1/2 of yoke is needed to be sticking out....

At ride height we have 2 1/4 u may need to go to the longer yoke i know when we ran a short one one night when we would come off the throttle we would get a vibration do to not enough yoke n the tranny and it bent the tail shaft
