Lonnie,
I'd be wary about having a shop replace the mount.
It seems like the authenticity matters a lot to you.
IMHO, the shop -
- won't understand how the mount works as well as you do now.
- will value functionality over authenticity.
- won't have or care to make jigs such as Denny mentioned to avoid collateral damage.
- will have to charge a high labor rate in order to protect themselves from rework due to the above.
YMMV, and after all, I've never been accused of lack of cynicism.
good luck to you.
regards,
Leon
