Depends on what rearend you have AND if the engine is in the stock location. That's why I measure every car I build. Put the yoke all the way in the transmission and measure center-center on the u-joints WITH the weight of the car supported at the rear axle, NOT the body. Subtract 3/4" from that measurement and that's what you need.

The car is on jack stands the 2 rear stands are under the rearend housing.Is it ok to measure like that.Just put in a 383 stroked to a 496.Only this driveshaft and steering column {cause i went to manual} and this thing should be ready to fire.Appreciate the advice guys

that should work-- but make the extra effort and grab a helper--- crawl under it with the car on the ground and confirm your measurement. Usually driveshaft shops will only make you ONE shaft---------If u screw up the measurement----you will have to buy ANOTHER shaft.....
