Thanks again for all the good input. I went with a large Siler and did some modification to the rear of the plate, i.e., made it a little shorter and redid the angle. I think it came out fairly nice.
Bill, I'm glad you mentioned the issue with the forward lock bolt... I was also concerned about that. Makes me feel better about my choice.
George, I agree with you about the M&G locks, I really like 'em, mainly because of that nice thick bolster. It makes getting the cheek area right alot easier.
Thanks again...
