Don't know if it's something you might try to do yourself, but if you do, make sure to use a rib center finder when you drill. They are available at Brownell's. Nothing screams "shadetree!" worse that a mid-bead installed off-center, and it is virtually impossible to get it perfect by measuring and punching. The eye will pick up any slight bit it is off center, at least mine does.

May God bless America and those who defend her.
