Slip Yoke Issue

Slip yoke supposed to slide all the way into the transmission output?

I had a driveshaft built according to measurement for my 400 trans. When the rear universal joint is bolted to the pinion flange, the slip yoke could actually slide in another 2 inches into the trans. The builder tells me this is normal. Could someone help me out here.

3/4" is a ton on our cars, ive seen people have 1/4" and not bust anything.

thats more for cars with leaf rear ends / bad geometry

i would get a longer shaft

sorry

That sounds too short, but I guess it also matters how long the splines on the slip yoke are.

Is there a lot of slop if you grab the shaft at the front and wiggle it?
