Default Repairing dash panels question

I need to repair the right and left side lower dash panels on my 68 convert where they join the center metal gauge panel. The places on the side panels where the screws join the metal gauge panel to the composite/plastic side panels are pretty much useless holding the screws, due to the panels being removed multiple times over the years. Prev owner tried to repair one side with some kind of filler, but it did not work well. Screws have nothing to bite into to hold. I am going to attempt to epoxy some metal self-tapping screw fixtures, but am not sure that is the best fix, since they will need to be dead center and they usually need to move a little. Has anyone found a good strong filler that will withstand drilling and holding the panel screws? RA

I have used 5 minute epoxy for application like this and it seemed to work fine. I did clean out the hole and reverse tapper the hole. Smaller at top larger at the bottom. Let it really harden and you can drill a starter hole.

Good luck and let us know how it works.

Hi r,
There is a nylon 'bushing' used in later dash panels that was placed at the general locations of the bezel screws on that edge of the pad.
The 'bushings' are designed so that there's some 'leeway' as to just where the screw needs to be in order to fasten securely. The 'bushing' is a longish oval shape.
If you want to consider using them I believe Willcox has them.
Regards,
Alan

Alan, thanks. that's exactly what I was looking for. I have a big selection of those little spring clips for self-tapping screws, but they are intended to go over the edge of sheet metal and slide, if you need to adjust them. Was not sure how to glue them so I cold move them a little. RA

Another solution.. And something I always suggest to have around to anyone working on these old cars... Plastic Fusion or Plastic Weld (two different names, same stuff).

This is the same style epoxy a dentist uses to make temporary crowns... It's great to use to repair breaks in any kind of plastic... and you can also force it into a hole, allow to cure and then re-drill the hole without having issues.

If you have a crack in plastic, you v-groove the crack, back fill it and allow to dry.... it's good stuff and available at almost any hardware store...

I have been using J-B Weld on my right side dash panel. Had quite a few areas that had seen better times. The J-B Weld worked like a champ for me and is real easy to work with.

Had used this before on my 68 Olds door arm rest which after all the years started to crack internally. Been good so far for 3 years! Hope this helps you.
