but unlike Thunderbolts, lightweight Galaxies and the like (factory finished or semi-finished, with w/vin numbers and or titled vehicles) what really constituted a "Ford commissioned" Pro Stocker? The older Logghe flip-top funny cars and SOHC Mustangs (short and long nosed) were factory backed and paid for by Ford. But by the time the Cleveland powered Pro cars came about, the deal was different. No vin number for bodies-in-white and I've never heard of a FoMoCo issued bill of sale for any pro stocker.
Keep in mind Ford did give away bodies, parts and bundles of cash to quasi-factory teams but I think it's a stretch to say Ford commissioned these cars. Could be wrong but it was always my understanding Ford gave out the bucks with the intention the team would (and did) have the cars built.
Btw, here's the article on Pinto bodies-in-white that first appeared, IIRC, in SS&DI......in a world long ago and now far away!
