Aaron, that is an awful lot of bore wear in the front for a new ring to survive.
~The proper way to handle that wear problem is with an over bore & new oversized pistons.
~If you call around you should be able to find larger pistons.
~If you just can't find any pistons or are on a very limited budget you can re-measure the cylinder bore at the top of the bore where the # 2 ring stops & if the wear is within reason there just install the new top ring in the # 2 piston ring groove & leave the top ring groove open.
~If the wear is just about as bad at the # 2 ring area you really should bore it & sleeve it or bore it & install oversized pistons.
~Even if you sleeve it, with that kind of [.030"] bore wear at the top I bet you will find the old piston has real excessive ring side clearance in the top groove.
