Adjustable Jack Shaft?

#1
I am building the jackshaft for my current built. The setup is a live rear Axle (fixed) to a jackshaft to the motor which is joined by a TAV 2 TC.

My question is, Do I make the Jackshaft adjustable? The engine plate is going to be slotted so I figure make the jackshaft slotted as well so I can move things around?

Just wanted to get some opinions.
