Hi Moose,
Well, you hit the nail on the head! So, how difficult is it to remove the
top plate?
Any special tools or knowledge required/recommended?
I'm fairly mechanically inclined, but a little leary of tackling something I
really don't
know anything about. I'd hate to ruin an otherwise perfectly good OM.
Thanks, Darin.
