There is a set of decent 70 fenders on craigslist for $250 (sent you the link)....I know shipping will probably kill ya from the location they are to where you are. SO maybe not an option.
I don't know. 14 patches? If they are THAT bad, my opinion is that you will spend a lot of time trying to turn turds into cream puffs. Yeah, it can be done...and it would be a learning experience....but you have to consider if you have that time and patience too.
At what point is saving some scratch by doing it yourself going to be outweighed by the sheer time and patience involved ? This varies for everyone. I have seen guysturn swiss cheeses cars into masterpieces....but they have the tools, materials and PATIENCE. LOL
I'd be either watching for used ones and working on the rest of the car in the meantime or just finding the cash and buying the repops. Or, as I said before , use the fiber glass ones for now...unless doing a quick and dirty bondo job on the steel ones would result in an easier/better aesthetic for now.
