Check with AMD. The thing with repro sheetmetal at least as far as 68-72 A-bodies, 67-69 f-bodies, etc. is that the rule of thumb is; if you are going to use any aftermarket panels, use ALL aftermarket panels. If you use GM NOS panels, use ALL GM NOS panels. If making body repairs, I'd suggest using rust free used panels if NOS can't be sourced. If you have to use aftermarket, you go into it knowing there will be extra work to make it fit correctly.

On my 86 K10, something as simple as cab corners required a lot of "massaging" with the repro corners I bought....but for $16 per side I knew I could make them work anyway.

1.) I had to re-create the rear cab side edge since the stamping was off compared to the production body line on the cab.

2.) The rocker-cab corner edge needing to be slowly and gradually ground down so that the rocker and cab corner met flush @ the lower seam.

3.) The lower edge where it is pinch welded to the inner rocker lip needed to be hammer/dollied just right so it "folds" up into the inner rocker to meet up so that the entire bottom edge runs straight along the rocker lip and cab corner lip.

All in all I spent 6 hours on each corner-most of it was modding for proper fit. I don't know if GM repair corners were ever even made/offered but anything an aftermarket repair part is being used, just realize nothing will fit as-is and it requires some creative thinking at times to get it to fit properly.

But the time/effort makes it worth it in the end.
