OhOneWS6:

My system looks identical to yours; although I have never compared these before.

The unit with the speedo cables going in and out looks identical to yours.

My 2 inner fender brackets look identical to TooMuchStuff's brackets.

So, I cant tell the difference.

I think that my Truck is, without looking, a late March 1972 or early April 1972 build.

My engine code stamping reads T0222XXX, being February 22, 1972.

Add....

As I recall, the 1972 year was a donor year for transitioning into the newer model, so I feel some things that are relative in 1973 were installed on 1972 trucks...or available in the 1972 year over the counter for 72 and earlier installations.

Tooling up for any changes in the truck series regarding the Cruise Control units I doubt were redone into the 73 and up models until maybe a later year period.

From what I recall from over the years, these truck CC systems were very similar from 72-78.
