Just currious what is all different & what years interchange?
My 77 monza dash is standard instamentation & I have an 80
rally dash cluster. From a quick look at it I can tell the wiring harness of
the 77 doesn't appear to have the extra wires for tach, etc.
The 80 harness is probably completely different anyway, so maybe using that as a comparison with the 77 is a waste of time?
The other thing, is the 80 dash gage housing (plastic) also appears
to have the provisions for gage mounting, were the 77 doesn't.
So does this mean the entire dash for a gage optioned 77, is different than a non-gaged car?
Or is it just the difference I am seeing between the 77 & 80?
Any thoughts?
