If you jump on Camaro5.com Needforspeed is making a knock off set in 20 x 10 and 20 x 11 with zl1 / 1le back spacing. If you jump in know there just shy of $1300 shipped.
I am not 100% certain of my math but I think these might just fit a 69 Camaro with an AME front subframe with Anvil wide fenders and a stock width (59.5") minitubbed rear end. Not sure how it would look though...
