Hey guys, I searched through the forums and didn't find the answer to a couple of questions that were asked of me today. I am in the market for a new drive shaft and went to a drive train shop today. I was armed with all the dimensions and info that I thought I needed; except he asked these questions as well:

What is the dimension (dia.) of the output shaft?

What is the inside dimension (dia.) of the pinion yoke where it mates to the u-joint?

Are these valid questions even though he has been told it is a 28 spline output shaft and a plain-jane 8" rear in a 66 mustang? Or, is he just giving it proper diligence?

Is $275 reasonable for yoke, shaft, and u-joints?
