Hi Buddy, Just a mention...Those screws are recessed square head. GM dealers have the tool that fits in there to hold the screw while the nut is loosened. If I figure out what size it is I'll stop back and put in the number.
A simple task of replacing a switch turns into a disaster! At least i am not the only one! lol. Those backup cameras are stupid expensive! Nice fix though! :)
Hey man going through the same thing right now and was curious on the size bolts and nuts you used! Tried the jb weld route and just as you said it broke lmao thanks for the help!
