1992 GMC Sierra XC, front fender bolts HELP!

[fancyTBI]

Well, I managed to get the passenger side fender and liner installed today. I dunno what kind of wizard you need to be to align these damn things but it seems impossible. The top gap is nonexistent while the bottom is 1/4". Even with all the bolts loose there was NO WAY to even wiggle any adjustment in fit. Same thing on driver side. I don't get it....this is just dumb

Just gotta loosen things up and pull/push stuff around. Super possible.

Are they OE fenders or reproduction?

Again, OEM fenders. IDENTICAL to what I removed. The set I removed won't line up either. What would have shifted?

can you share some photos? That might help. You may need to make some of the holes egged shaped with a die grinder so you can adjust them more.

Are the front cab mounts in good shape? you can add shims to raise the front of the cab to give your self more adustment leeway, also try tightening the core support bolts down a bit to lower the core support.
If the top of the fender is tight at the door and the bottom is loose add a shim to the bolt on the bottom hinge bolt.

I forgot about the shims. Nice job for pointing that out.

Seems like your asking for advice and don’t want to take it. Did you separate them as pointed out?

Just because the factory fenders fit does not mean that new fenders are going to fit exactly the same.Go buy new core support mounts, install them loose and get all of the fender bolts in while they are still loose. Use shims to align the fenders. It takes some doing to get it right, it is not just unbolt and install new parts. It takes practirce and Patience to align body panels.

Another thing, the top flange of the fender that sits on top of the core support might have to be bent up or down to get the lower bolts to align.
