Guys, everyone's car is different...Don't assume any length is the correct one for your car...There's just too many variables with suspensions, drivetrain components, etc... Best way to check for your length would be to set car at ride height with a full tank of fuel...Get the front yoke you want to use and push it in until it bottoms out...Then pull it back out 3/4 of an inch...Be sure to have the universal saddles parallel {at the 3 and 9 oclock} positions on the rear and front yoke...Then measure{at what would be the universal cap centerline} what you need for your exact shaft requirement...This is the only way to know what you need for sure...





However, I have used the same DS I measured in both Gina's 72 which is set up at as a street strip car and has a stock leaf rear and my 71 which is lowered and has a 4 link rear.

FWIW, I could probobly use a DS that is a 1/2" shorter
