I'd run that, not effecting the compression of the oring, and looks like not enough for the oring to walk out the groove. I could be wrong, and I'm sure others will have a different opinion.
You can always try jb weld, it works miracles some times. If it fails just put it in the yard-a-pult and give it to the neighbors a couple houses over, go on ebay, get a used one and problem solved.
It’s one I had in my pile of parts. I was going to send it off to Group K and have it milled
and swap it out without missing any ride time before the season is over.ill just wait till Dec when the seasons over.
Thanks
