Slant six timing issues

Not related exactly to your problem, BUT, if the ring has slipped you need to check it real good. If it comes off because the rubber is shot you could have a real problem. I had a couple rebuilt by a company out west for a few bucks each. They just need a good core. Message me if you want the company address.
Is it more cost effective than getting a new one? Im located in southern California and its looking like 190 ~ 200 new. Might hit a pick n pull to see what i can find.
