All the mounting tabs the hold the gauge panel in place are broken off on my 1970 dash. The homemade gauge panel was held in with zip ties, now I know why. I think I have one located but I would like to know of any tricks that has been used to repair one. The rest of the dash is in good shape but the plastic around the gauge area is very brittle. I was thinking of trying some JB Weld to glue some plastic angle brackets in place. Help!
