New 70 SB owner "Couple of questions"

[murguia]

So I just picked up an all original 70' CST 10 shortbed with: Original pain, A/C, Tilt, Tach/Vacume, wooden bed, PS, PB... It's two tone hugger orange and white with a little rust in the corner cab and front bottom fenders (Not a lot).

I noticed in the rear fender wells, the sheet metal (Or inner fender well) has like little evently distributed welds is that original? I've seen this in a few trucks now..

Also the 2nd owner put on some blazer rims which I'm not a fan of, I want to put stock steel rims with the 70's style hub caps (15") What type of rims am I looking for exactly?
