What timing cover are you using with a 7.3 inch damper

Well in Australia, this( whatever this is) is the only one available.
I just installed that exact balancer and there were no issues with the timing cover. As a matter of fact I pulled off the 18 month old scat balancer because the painted on timing makes came off. Its even machined to allow you to line it up before the tolerance fit starts.

Let me know if you want any pics
