Tim,
The repro steel inner fenders are most likely going to give you a hell of a time. I installed 2 new repros on my 70. One side fit nice, the other was a total wrestling match for me. i ended up having to redrill the holes to make it fit. unfortunately, all the repros are made by the same overseas manufacturer to my knowledge. They can be installed with the fender on the car. Best thing to do is take your time.
Tom
