Thought I'd catch you up on my project. This is what I did.
Using a Dremel cut off wheel, I made a cut into the bezel; then spread the bezel enough that it cleared the peen.
I thought I'd be able to file the peen down enough to force on the new bezel - no luck.
So I started to file the peened key so that the new bezel would drop on.
The new bezel had a smaller hole and perhaps better tolerances because I also had to 'square' up the top of the shifter handle so it would sit flush.
Once that was done, needed to decide how to fasten.
I believe there would be enough material to drill and tap the handle for a #4 or #6 machine screw; one on each side of the keyhole would work and make it serviceable. But, decided not too.
Considered silicone but was not convinced of its adhesive strength (probably would have worked)
So, I went with J-B Weld...and probably too much meaning if I want it off...it will come off but it won't be pretty (but I don't think I'll need to remove)
So J-B was slathered onto the shifter handle and the bezel affixed. Made sure some formed a new peen.
BTW, I've seen folks ask about how to get the shift pattern lens out...I was able to pry it out with a utility knife blade...thanks to old glue I suppose
Something I found interesting was that inside the pistol grips themselves was some green clay-like stuff that I am guessing is not factory and that a previous owner put in perhaps for better feel...or vibration 'buzz' control?
Who knows?!?
Nevertheless, I had a quart of flex seal that I bought for something else (a quart is a lot btw!!!) and figured why not fill the new ones...nothing to lose.
After the new lower bezel was 'rawled' in and grips screwed on, a few more dabs secured the new lens.
And done...
Hope you enjoyed the ride!!!
P.S. Took home a "Most Original Mopar" trophy at a small local show this past week-end. ("original" meaning true to form example/restored, not survivor)
