Restart the rebuild

Not much gap between slinger and chain. 032". Seems close. I'm all for using it but seems like a gambler. I've got drip tab and bolt with hole.
Opinions?
Thanks

Ive had them hit with a double roller chain and not hit with one. I don’t know why a couple hit and the rest didn’t.

Rather than spend a bunch of time running down why they hit I just don’t use them. In retrospect I probably should have figured out why but I’ve never had an issue without one.
