Thanks Guys!
Spent another 8 hours on it today. Fabricated and welded up repair panels on the engine compartment aprons and in the back side at the firewall. I'm off again tomorrow, so another 8 hours should get the cowl notch repair completed. We're ordering up some paint to do the inner cowl area, so that will be the first silver paint back on the car in 35 years! Once I get that cowl notch repair in place, I'll get a couple more pics posted up before and after. Its taken much more work than I expected to get those areas cleaned up, but its all worth it.
