Thread: Radio Mounting

  1. #1

    Default Radio Mounting

    The dash on my 79 Pace Car is very, very brittle. I had to remove the console and dash to replace the heater core. The radio stem on one side was broke when I took it apart. Is there a good way to repair this other than to try and glue it back together....which might be impossible. Also does the radio attach somewhere other than the two stems.

    Thanks
    Bob

    The radio usually has a metal bracket that attaches to the back of the radio and then is bolted to the metal support bracket of the dash.

    The dash can be repaired using a good automotive quality adhesive. Most general purpose glues/adhesives can be hit/miss in this regard. I generally use 2 part urethane adhesives as they are stronger and often will help repair the old, brittle plastic. There are plenty of options depending on your personal needs/choices.

    Thanks for the reply. I need to find a bracket, mine is missing, which I imagine caused my problem.

    I'm going to try and create a repair part and use JBWeld.
    Thanks again

    I have not had good luck with regular JB Weld in this regard. I would recommend trying their clear epoxy product. It seems to wok pretty well on different items and some plastics. I still like a 2 part urethane over the epoxy for the dash, but definitely worth a try if you don't other options.

    If your stereo is not OEM, that might explain the lack of bracket. Most aftermarket stereos either have stud or a threaded hole in the middle of the stereo in the back for attaching a brace/bracket to for added support. Good Luck!

    I've had good results with this: https://www.plast-aid.com/

    Used for small repairs, in particular the mounting tabs on the dash pad.

    I thought there was an over sized metal plate on the front for the factory radio but Iím probably mixing it up with the 78. There was also a rear mounting bracket. I just saw one on eBay for 79-81, D9ZF-18888-AA

    I did a restoration on my dash that had numerous cracks in various locations especially in and around all mounting holes. I used West Systems two-part epoxy mixed with microballoons and some places I mixed it with fiberglass strands for added structural integrity. I’ve been followed up on the front side with a light sanding and graphite SEM interior paint.
    As stated before you will certainly need the bracket in order to carry the load. The OEM radio it’s very heavy and there’s no way the face of the lower dash will carry those loads.
    Another possible option on the backside of your dash would be with Bondo infused with fiberglass. You can get bondo with both fiberglass gel and strands. I consider this for structural pieces; however, did not use it. I had the epoxy and Microballoons laying around the shop.

    The dash is ABS plastic. You can make a glue out of scrap pieces of the ABS and acetone. Mix until you get a thick like glue. You can glue cracks with just the acetone, just like super glue.
