Default C1 dash insert question

Just removed the dash insert assembly behind the grab bar to replace the aluminum insert and have a qusetion. What are the two threaded nuts spot welded on the inside of the backplate used for? There was nothing attached to mine.

They are for two short 1/4" X 20 bolts. I don't thing anybody EVER puts them back in. You really don't need them . Just use the three studs on the back, and it should be fine.

Getting everything ready for the windsheild/dash pad replacement and this is one of the first things I'll need ready to go back in.

some comments on the insert....when you put it back together with epoxy you have to be careful to get enough to hold it but not so much that it makes it nearly impossible to get apart. I used too much when I put it together an upon installation of the insert back into the dash I marred a corner of it. It bothered me so I took it out and replaced it again. AGHHHH, nearly messed up the stainless that goes on the edge because I had used too much 2 part epoxy. Word of warning there.

Second when you put the bezels over the ends of the grab bar, you want to make sure that you have the insert properly positioned. When you push the bezels out to the ends, if it isn't sitting right those bezels can easily marr the surface (see my note above about marred insert and taking it back aaprt, this was how I did that).


That was my learning experience on the insert.....good luck!

Well - this is how much epoxy I used...can't say if its too much or not...
The epoxy sure can't be any harder to remove than grinding off the spot welds used for the original attachment points..

Don't "dis" that old screwdriver Mike. That has mixed more fiberglass, bondo, JB-Weld and two part epoxy over the years than I can remember...probably 100 pounds or more. I'm passing it on to my heirs...

Besides I remember you bragging about your ancient Binks paint sprayer...

the problem is that the epoxy will get into the cracks and crevices......and if you ever try to get it apart, it isn't as easy as grinding the welds off, that was easy. When the epoxy gets into the crevices the stainless trim will want to bend because the epoxy doesn't want to give up......I should have mentioned that little detail, the crap flows into places the weld never did....

When you go to purchase a new dash, the best deal is not always the best deal.....they are 'NOT' all the same....

hmmmm.... considering all the successes i've had with it, i think Ultra Black RTV might be a good alternative way of attaching the molding...

might be if it doesn't flow into the crevices....if you never need to take it apart, it isn't a big deal. My first one went together real nicely, but taking it apart was a bear, I even used high temperature to overcome the epoxy, that was the only way in the end.

The least amount of adhesive is the best way IMO.

I don't know how much that particular epoxy really 'flows' into crevices...it was pretty thick when mixed properly. Not that its keeping me up nights but I think I could get things apart if I really had to...wouldn't be fun, but I could do it..

I went a little overboard with the adhesive because the thin trim pieces had a tendency to pop up in one place once you got another place seated properly and I got sick of fighting with it.
