I can remember where I got it now.
Someone on eBay had like 50 of them
asking $20.00 each but I never did see
him sell any. I suspect if you decided
to speed up the disc was gone if you
didn’t take it off. I’ve seen several
clips on Pals and Rangers.
Even saw one on a Cub once.
Here is another brand. (Go Slow)
Looks like they would stay on better.
A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
