at some point my stock side view mirrors were removed and the mounting holes filled with bondo. i bought myself some nice repro mirrors that i want to mount.with out any experience in this area im thinking about a hammer and a punch to break it up and the a tap to clean the threads. any better ideas? cause thats all i got.
is the surface painted..most mirrors are mounted with self tapping screws..you can probably mount them .. either with RIV NUTS or WELL NUTS..i don't know how gm mounted the mirrors to 53 3100 models...there are also neat low head allen bolts.. give it a different look... use the stainless versions to prevent rusting.. http://www.mcmaster.com/#catalog/117/3104/=nglsj1
this image might give you some ideas..
so i shouldn't attempt to remove the bondo in the mounting hole. i should use self tapping screws and go through it? i like this much better. oh and it isnt painted. its in primer. i have to run to the hardware store today to get more button head bolts for the fenders and i will grab the hardware for this and get it on. thanks.,
