I understand what you're saying, but when you need a complete front clip and the fenders you find are beat up or a rusted piece of junk who wants that on their car, not me.
so you want everything to be easy and at your fingertips, to able to just fill the cart and order up your front clip. got it.
the **** is out there though. it's not tough to find. it might not be cheap, it might not be next door, but it does exist.
this may not be the golden age of A body mopar (yet), but there's 10x as many parts now than there were 10 years ago. AND the inter webs have made contacting and finding these parts infinitely easier. so don't come in here swinging on my gate with a whinge about how there's no parts for early A's
also, if your buddy scrapped a car over not being able to get some interior parts then most likely, the car was a flaming pile of **** anyway. you don't scrap cars over inconvenient interior details, that's what they made Mexican blankets and duct tape for. duh.
