Just to update for future viewers.... I found and mounted an old weaver T1 mount. The holes line up perfect, but I did need to shave about an 1/8" of the stock to get it to set flush. Since mine is a beater rifle, it didn't bother me. Also, the T1 is pretty close on bolt clearance. I have a straight tube 4x scope, so I had no worries. Hope that helps someone in the future.
