Not being a purist, the locals where my first reaction. I'm close to Summit so generally my go to, but no luck there. Looking into some possible cross over, I found that 68-70 B-body is very similar but has a vent hole. E-body did not. Probably the reason it rusted in the first place. For 35 bucks its worth the shot. I'm really surprised no one has come across this problem before.
