atc 70 chain

[Tucker11]

I'm in the process of getting a 85 atc 70 running, and was wondering if they make o-ring chains that would fit.

Any 420 and possibly even 428 sized O-Ring chain will fit, assuming it's the correct amount of links. 428 might be too wide to fit into the sprocket area or might rub, so I don't know, but a 420 will definetely work.
