Got the new tumbler today and planning to drill after looking at it -- There is a small pinhole that lines up correctly when the key is in position 1. If I can drill at this correct spot, then it should be super easy.
Only problem is -- Can anybody here tell me which way is "up" ? Does that metal piece at the back reside at the top or the bottom when the tumbler is in the correct orientation? Obviously there are only two choices.
Here:
EDIT: Managed to "just" about find one that gives it away

Fingers crossed gonna see if this works
At least by the end of this, anybody else who has this problem will have pictures and directions on how to DIY it.
