IMHO, the repop parts are junk. I bought a RS clip kit and could only use a couple parts. When I tried to assemble, almost none of the parts would line up. And, IMHO, repop fenders are junk too.
I found a fellow in Wisconsin that had an RS front clip. Bought it and within 1.5 hours, I had the entire clip, excluding the hood, bolted on and lined up.
That's just my experience. Good Luck
