Interesting trivia... what factory optional rim was made by Cragar? I wish there were many answers, but the only one I've come across is the 1983-86 Cadillac Eldorado and Seville

if you know of some others, please note it in the comments.

I think it was cool of car manufacturers to use aftermarket companies for performance parts, like the Edelbrock 6 pk intake on Mopars in 1969, and the Hurst SC /Rambler having glasspacks.

But when I came across this, I was disappointed to find that there doesn't seem to be a simple answer online of what cars had Cragars from the dealership or factory. Just this Cadillac answer.
