Interesting idea. I never would have considered the wedge as an option. I'll try that for sure, thanks for the suggestion.

 

I needed one for my lfca's. I just measured distance across holes, then went online and found one with same distance, then ground down diameter of tips to fit holes.

 

Another great idea. I just went to Harbor Freight today and picked up a pack of 5 pin punches for about $7. I tested it in the original, the 1/4" punch fits perfect. When (or I should say if) the new collar arrives, I'll start the install. It's killing me waiting for such a small component. I've sure matured over the years. When I was in my 20's an 30's I would have started without it... And many of the required tools. Now I over plan for everything. Lists and checklists! Life is funny.
