Driveshaft/yoke question

Running into a problem on my 95 Z28. Car has a freshly rebuilt T56 with a viper mainshaft and a 9 inch Ford that was previously in it. I had to purchase a new yoke being the splines on the viper shaft are different. The yoke that fits the viper shaft is longer that the one that fits the stock yoke. My concern is the amount of travel that the driveshaft has when the suspension is loaded. I havent placed the vehicle on the ground and I'm already a little leary about how much the yoke can travel inwards before it bottoms out. Is my only option on this to have the driveshaft shortened? Thanks for any help.
 
There should be 3/4 to 1" of travel.
That means at ride height (tires on the ground or axle housing supported by jack stands holding weight of vehicle) with the slip yoke installed all the way until it bottoms out or touches the seal, you should have 3/4 to 1" travel to the slip yoke.
Keep in mind, this distance decreases in most vehicles when you allow the axle housing to "hang" and support the vehicle from the frame.

The yoke should travel all the way, or until it hits the seal. If it bottoms out before hand, than yes, you can machine the end off to make it shorter.... either that or purchase the correct yoke (preferred method)
Driveshaft travel should still be measured exactly as I described.
 
Yes mine was hitting the rubber bumper inside the t56 and still had like 3 inches before the dust seal was even close
