Unlimited Fiberglass

I've heard their stuff isn't so great, but I'm looking at front and rear bumper brackets, and headlight buckets. Car is a '74 Dart Sport being cloned to a 70-71 Duster.

DUSTER & VALIANT 67, 70-72 & 73-76
- PL-306R&L
- PL-319R/L
- PL-320

Which would be less hassle; using their bumper brackets, or making aluminum?
Do the headlight buckets work, or should I find steel? I don't even know if the original steel buckets are part of the fenders or separate. I've never seen an original fender.
I already have bumpers and a hood from Glasstek. I have fenders that I bought from a member. They've never been mounted, but he didn't know who made them. -No buckets in them of course.
