Our DMV is getting better as they learn. Being a small place it took a couple of years to get them to even look at the Memo that were issued. I looked at one of the guy's registration slips last year and it said 2004 1965 Cobra Replica on it. The BAR guy spent several minutes telling him what a nice car it was and then did the snifer test. He said the BAR man then put the sticker on it and that has his 2004-SPCN number on it plus smog exempt. And you are right that the BAR does establish what if any smog equipment is required. As for the 1980 example, then you would go by the engine year and get an old engine. As the bill states, the choice of which to go by is the owners and not the DMV or BAR. Default for both body and engine is 1960 which is even better. And Maurice lives not to far from me and I have talked to hom many times about the laws, even back before he could get SB-100 passed with the 500 limit. He got around this mess with his Lone Star by pretending to be a dealer and he drove it for a long time with dealer plates.
By the way, that is a cheap way of getting a Ferrari. I would never have guessed from looking at your pictures.
