Bonjour. What's the diameter hole that has to be bored in the case for the AA Performance jugs for 90.5 (1776) and 92 (1835) bores? Pretty please if anyone knows...

berg had some smaller 90.5's but that should work for the aa 92's.

Thanks gents.

actually to be specific that's the cylinder itself. Case bore should be .005-.010 bigger IMO
so 96.1-96.2
