Thread: Hi Tech Gap Filler

Tweet

How about using the aluminum shims used for adjusting pinion angle on rear ends. They are available in different angles of degree. They can be cut to fit and polished. It would be easyer than trying to sand the angle with a belt sander.

I have used JB weld for stuff like this . first thing to remember , JB weld or anything else for that matter loves to run down hill, get the quick set. I used some alum. tape to make the sides of the gap you are trying to fill. You can pull the tape off a little, then fill and restick the tape. This way will leave perfect clean sides once done. I also put the JB weld in a little baggy and cut the tip to "inject" it between the two. Tape everything, even pull the mirror off and tape the 2 surfaces . This way you will have a made shim that will not be stuck to either, unless you want it to be stuck to one side. I have not tried the other stuff.
Or do as ALLEN said use a aluminum shim then polish it up.
