it's funny, at the fling i had several sets of rebuilt OE uppers with offset bushings and good quality ball joints (both big and small) for sale at basically the same price and nobody seemed the least bit interested in them at all.
Because they don’t include the important lesson that free stuff can cost you a lot of money!
While this is not true of everything, I would take good condition OE UCA’s over any of those imported reproductions. You know the re-popped stuff isn’t the same thickness. Of course, I wouldn’t install NOS bushings or ball joints in them.
