Upgrading Door Locks

That's a good point about the notches. I will make sure that whatever punch I get is the right diameter; if one exists, then file the notches to "key" the lock in place.

Thankfully I have bare '68 doors to make all the measurements from and check that the punch fits through the '68's hole, as well as measuring the lock cylinder itself. :-)

"What did you call me? A '68's-hole?" :grin: (ok... not that funny I guess)
