Re: Stripped bolt holes in dash
I believe they have clips in there that the screws go into - maybe you can replace them. I think they look like:

Called U-type Spped Nuts - Scroll down and look at like part number 700-542
Most auto parts stores carry these in the HELP! section in a box that has various sizes.

Re: Stripped bolt holes in dash
Thanks for the quick reply!
For some reason I thought it was just plastic holes in the dash where the screw/bolt goes. I will go back in the garage and look again.

Re: Stripped bolt holes in dash
they are plastic posts, they strip. Use a slightly larger screw, thats about all you can do. unless you can fill the hole with epoxy, and drill it back out to the right size

I would use J-B Weld or a slow cure epoxy. Just remember the faster cure time epoxy will get brittle over time faster than slow cure. I have not seen J-B Weld get brittle.

Re: Stripped bolt holes in dash
I lean towards the cold weld due to you will be using it to dill and put screws in. That stuff bonds better and almost seams better than original, once you're done.
I would get something to test it on and see how it works. You will be impressed. That is if you mixed it correctly. Also make sure you clean and prep the whole to be fixed. Any dirt and it will not bond properly.

Re: Stripped bolt holes in dash
Get a Set of Helicoils. Drill out the hole to the size called for in the kit for the Thread size you need. Use the provided Tap on the hole. Be Careful since the hole is PLASTIC, not metal. Once you have drilled and tapped a new bigger hole, screw the Helicoil into the hole and you will have a Stronger more professional looking repair than OEM. You may want to set the Helicoil with Thread Locker or MAYBE Super glue, but only AFTER you've installed it. If i were to use the Super Glue (I never have tried it) I would use a VERY small amount right at the top of the repair. you wouldn't want to get it on your nice new threads. The purpose is only to keep the Helicoil from backing out. Just make sure that if you go that route, you apply the glue AFTER you have completely installed the Helicoil.

Re: Stripped bolt holes in dash
The epoxy fix is the best repair! Larger screws don't look stock and other fixes require making the damage worse! Just put some epoxy on a toothpick and coat the inside of the oversized screw hole. Make sure it cures 24 hours before you put the screw in.

Re: Stripped bolt holes in dash
The Helicoil Repair would allow him to use the stock screws. The only reason he would have to drill the hole larger would be to insert the Metal Helicoil. The Inside of the Helicoil would have his old thread size. Trust me, The Epoxy repair would look Horrible and wouldn't be as Strong. I've been a Machinist in the Navy for 4 years and then the army for 12 years. Helicoils would make a nice repair. Again STOCK SIZE screws.

Harbor Freight or Sears would have what you are looking for.

Re: Stripped bolt holes in dash
I hereby Apologize to Wdigitog. Since i have to replace my cluster as well, i went outside to remove it. I noticed that all the screws involved were self tapping or sheet metal type. There are no Helicoils for this application. It seems to me that the only course of action would be epoxy. I'm sorry to have misled you jprix. Perhaps in another situation, Helicoils would be a neat clean repair, but not in this one. Next time perhaps i should do some more research on exactly what the application is. Again, i'm sorry to anyone i've misled or offended.
