I think they would look good.
I'm not crazy about them on a 69 Camaro, just my 2 cents. Can't go wrong with Forgeline though. I would check their website, they may have a gallery of 69 Camaro's with those excat wheels on them.
GOOD LUCK!!!!
I think I have an eye for what looks good or bad...in the Camaroworld mostly,and I am not a big fan of really-moderne looking wheels on an old car...just my opinion if you ask,I think there are other mags that would look better on a 69... certain Forgelines on 4th Gens,thats a sureshot
