Question about drive shaft

[ivorton74]

Im getting my 5.3/4L60 swap from my old 74 c10 swapped into my 83 c10. My buddy tried fitting the driveshaft that we had made for the 74 but turns out its too long. The engine n tranny are sitting a bit further back in the engine bay of the 83 so thats one reason why.

However the 74 was lowered when we measured to have the driveshaft made n the 83 isnt lowered yet. So my question is does it make a difference if the truck is lowered or not when measuring for a driveshaft? Im taking it to get it shortened tomorrow n also have to swap out the u joint since the 83 has a 10 bolt rear end.

Forgot to mention that the yoke is all the way inside the transmission
