Patch, or Replace inner fenders?

TTI was not in business decades ago. Yep racers are not always neat either. Personally I would use original metal if available for sure, second choice or maybe first choice UNLESS it is a car that will be worth some $ or cherished like grandma, is do a god job of patching, there will ne undercoat on the underside, like factory, and not hard to do a good job of welding, grinding, a skim coat of filler. But I get in a hurry to drive and not spend decades getting there.
