I am in need of the cylinder skirt outside diameter of an ESR 370 cylinder.  I am going to prep a set of cases myself to save a little money. Thanks Loren

If I'm not mistaken it's 3.4 inches.  In talking to Arlan about it on stock cases he fills void with epoxy since the milled area gets pretty thin
