Aftermarket inner fenders (67-72)

[54belair]

Im sure this has been discussed a bunch--just didnt find it, But----

Ive been looking for a perfect right front inner fender-----I know, like hens teeth!
Anyway, my question is: Has anyone actually used an aftermarket inner that didnt fit? Ive heard nothing but horror stories about poor fit on all of the aftermarket units------------if they fit poorly, be specific on what the issue was.

thanks guys
