Most of my knowledge comes from first hand experience. I paid for several restorations by parting out 71-73 cars. Knowing what parts were valuable was key, and the CJ pan as I used to call it was a good one. I've had two 72 351CJ engines that came out of wrecked/rotted parts cars. Both had the baffle and scraper, and were untouched as far as I could tell. Almost every one of the dozens of 70-73 2Vs I've owned had at least the baffle plate in the sump, think I've seen maybe one or two without. At least one had a the Boss/CJ pan. Can't quantify which one was which, nor did I check dates or stamps on the pans. Two years ago I bought a very early (105xxx VIN) 71 351-2V sportsroof that looked like it got used in a Dukes of Hazard stunt, with a stuffed oil pan and bearings to match, also had a baffle in the sump. Motor was very original, down to the Ford bearings and fifty years of goop in the pan. Going to say that I also read articles of the years stating as such. There are several others here that I trust, that have had similar experiences.
As always, it's "never say never" when we're talking about an assembly with production schedules.
