Just wonder what the correct length should be for a 69 dodge superbee with a 23 spline 4 speed and dana 60. Need to get one made up for it. We added the dana and the one we have is too long and we need to get some length taken out of it. Thanks for any help.

Push the yoke all the way into the trans and pull it back out 1/2 to 3/4 of an inch then measure from the center of the front U joint to the center of the rear u joint area in the rear end yoke. That is the correct way to figure out the shaft length you need.
