Ok, I am converting a column shift 3 speed to a floor mounted 4 speed (yeah i know, me and everybody else)

My question is: What are the differences between the rods for Hurst shifters and Inland shifters? I'm intending to use a later model OD (of course) 833

(I'm using an inland)

While I'm at it, are there "spec's" published for the rods?
