Shooter: Thanks for the quick response. I kinda thought the hex head bolts were the ones. I tried to back one out last night but it was really tight--thought I would post a message and verify before breaking it loose. Looks almost like an aluminum plug--sure hope it isn't seized. I like the hex bolts when they are get up around 10mm or bigger--have a hard time getting necessary torque on the smaller ones. Guess I'll get after it today. Thanks again. John Downey
