68 Cuda grill studs............ Any tips ?
I have a few sets of grilles apart as I'm learning straightening & polishing. What I did was remove the vertical bars that the studs mount in and install speed-clips and I threaded in stainless steel machine screws w/ brass nuts & lock washers. If I get a chance I'll snap a picture of what I did to mine. But you DO have to dis-assemble the grilles, removing those small rivets that I still haven't found a source for yet.
Now you know why those grilles are worth so much. Lots of stamped aluminum that bends and gouges, mounting screws that snap & strip, and very hard to polish & restore.
BTW: Sweet garage and it looks like a nice solid `68 project car. Good luck with your project!
