Thanks much - glad to be of help!!

If you have the skills - and recreate everything from the originals - you should be much better off than I was with the PUI covers!

I bought everything at once from YearOne to get the 25% deal, so the strobes came through them, but the vendor was Dante I think. Phoenix Graphics is another good vendor, that's where I got the decal kit above.

The rear brackets I cut, removed 1.5" and re- welded, the fronts I slotted the original holes 2inches with a die grinder. Worked well. Those are the original bumpers, rechromed for $350 each(ouch!).
If you have time, here's the build on CC.com - it's largely the same, but has some different pics as well... Chili Challenger build

Looking forward to watching more of your build!!
Cheers!
