Moving forward on the 77 K10 restoration. The p/o had installed one of those aftermarket tubular chrome grilles. I am going back to stock, so I purchased a new grille from Brothers. But how is the original grill supposed to mount? It seems obvious that the 2 center mounts are screwed into plastic nuts that are snapped into square holes in the radiator support center bracket. But the 2 mounting points on the left and 2 mounting points on the right are out in space with nothing to screw into. Are there supposed to be brackets coming off the radiator support? I see weld nuts in the radiator support where a bracket might go.

I have searched in Brothers, LMC, Classic, etc. Nobody seems to have any such brackets. I can find grille brackets for 73 - 74 grilles.

Thanks for your help.

See pic below- on mine, and I assume yours is similar , there are 2 vertical posts and there are square slots where those plastic pieces slide into for the screws.

Maybe someone else will have a pic with the grille off.

This is the upper drivers side.

Thanks. It looks like there is a steel bracket in there that comes off the radiator support and comes forward to meet the back side of the grille. Is that what I am seeing?

OK, now I think I am convinced. Seems I am definitely missing the bracket circled in red. Guess I am searching for a used set since nobody seems to make these new.

That would be super. Do you know if these brackets are year specific? I have to believe that 73 - 74 are different because there are new/re-pops available. And they look very different in shape from the ones I need. And I see that starting in 1981 the rad support was also different. So is it safe to assume the brackets are common from 1975 - 1980?

Also, I read something about there possibly being difference between the Chevy & GMC grilles in terms of mounting locations?

Yes 1973-74 used a single screw on the ends and the center support is much more recessed that 75-80. 81+ use a somewhat more complex grille mounting as is cannot simply be unscrewed from the front of the truck. But afaik 75-80 should interchange without issue.

My tube grill had its own sheet metal supports that it was installed with. I had to go to a junk yard and pull the original grill supports.

At this point you probably already had this answer though. I just went through this 6 months ago.

I can't find a closer up pic with grill off, but here I have the brackets installed after I painted them and before I put in the original grill I also pulled and restored from the same truck.
