I was a member of the POCI-S.O.S just for 60 Pontiac owners and have a stack of stuff on those and the early SD parts still and some misc. from the cars. One funny thing is the Ventura was billed as sports model of sorts but they also made a 4door hardtop in 60. I wanted to find a Catalina convertible and add all the Ventura trim and interior to it as a what if car somewhat like the X-4oo. Then I bought 64 Falcon with a 289hipo and even the Firechickens found new homes.
What is amusing is that Ponchos seem to have a soft spot with other Ford guys too. Most of what I see posted here is more accurate to what I learned owning them than what I see on the Pontiac forums.
