Greg,

Yes, a great help. Many thanks indeed. I believe there are variances/inconsistencies on SPID "protocols" depending on the operator, factory...could've been a new guy operating the SPID maker, or the regular guy called in sick that day.....and who knows what else. A blinding flash of the obvious, I have a 72 Sierra Grande...I'll look at that when I get home today....and a 72 Cheyenne Super. The "000" in the wheelbase block on my 70 GMC puzzles me....never seen that before, after 32 years of playing w/these trucks.
