1970 aluminum slotted wheel questions

[LeeP]

That site is very good and my head is now spinning. Lots of good information. Ansen had some competition by 1970. My car is a fully documented olds 442 w-30 convertible ordered with poverty caps. The car just debuted at the MCACN show in Rosemont. One month after it was ordered the first owner replaced the rims with the slotted mags. The car was delivered in California March 1970 so it looks like Ansen would be the first choice but the other brands would be correct too. Got this below from the site you provided.

All the early Slots had the bolt on caps till about 1970 depending on brand, Ansen in the 70s offered both bolt on and a metal pop-in on their Sprint IIs, also Ansen offered them polished and in direct bolt and a mult-pattern in the 70s
