I converted my 77 CH to 1979 rear disc brake with all OEM sprocket cover, internal shield, M/C and linkage. I'm running an 'o' ring chain with a 22 tooth and have no side clearance problems. When it was OEM 1977 and a 24 tooth the non 'o' ring chain 'customized' the internal shield!!!

Or, in the case of an old worn chain, there are places that are more stretched than others (this really shows up when the chain needs oil badly).

I'm 90% sure the battery acid is a non issue with the chain. It was washed immediately and coated with a heavy does of chain lube and an industrial WD-40 type spray. No other signs of corrosion. I think the battery acid just led me to notice the chain a little closer. All the cracks are on the tire side, which is wear the chain was rubbing the battery tray at the bottom of the hard tail.
As far as the O-ring chain, I have had some stretching but never any clearance problems. Both my sprockets are stock with no sprocket cover on the front. I'll look again for any rub spots, but none that I know of.
So, I'll pony up for new sprockets and go ahead and do the rear wheel conversion. As far as chains, I've always heard o-ring chains were better, if I solve any clearance issues, is there any reasons for one chain over another?

O-ring chains are lower maintenence, only an occassional shot with lube mostly to prevent rusting.

If you're gonna pop for an o-ring chain, check out x-ring chains. All the same benefits, fewer drawbacks. I thnk DID is one manufacturer.
