Your actually in pretty good shape if you need to have a ring made. You have one correct ring already so just one needs to be made and you have a pattern for the feet of the one you need made. You could also have a sleeve made for a slightly smaller objective housing.

Weaver Grand slam rings are steel and the tall/ X-tall have a good chunk of steel under the ring to carve feet for a claw mount ring.

After the first shot the rest are just noise.
