Subject: More than you ever wanted to know about lock cylinders
Ok, here's a dimensioned drawing of the lock cylinder I'm
looking for, and the ones that come in the new Brazilian baywindow
door handles and one I picked up at the Antonio VW parts counter.
Bottom line, the old cylinder is smaller in diameter than
new ones (0.470" versus 0.530"), and the crowns of the wafers
are wider (0.168" versus 0.208"). So I'm going to try finding
old 0.47" cylinders when I visit the junkyard, then see if I can
make a new tail-end piece to fit, since the new ones, at least,
are shorter enough that I think there's space. Looks like I'll have
to cut back some of the boss on the end, but I don't think this
is that big a problem. There's a lot of metal between the end of
the keyway and the end of the boss.
Of course, I'm going to try all the local lock shops, and I'd
ask if any of you have a box of lock cylinders, or see some, to
look for these jewels! I'd be happy to pay for one or two cylinders,
with or without keys, as long as they're intact!
Cylinder from "Witte 261 829 561C" latch on my '70 single-cab.
This is what I want to replace!

Obvious kludge plans: Build a little extension that
uses a common door lock and drives the cargo latch:
