Thank you 64Cheyenne, Garvin, ParadiseM for the warm reception, time, and effort. I will trek out to a junk yard for the initial search for parts, but Rock Auto and the C.C.wanted section look like they will fill in the gaps.
Garvin: I have a fair amount of experience with locks and the manipulation and repair of the tumblers is, unfortunately, not the totality of the issue. I believe, due to the natural and prevasivness of the damage to various structures of the locking mechanism, that there was a mechanical problem with the door that was not addressed and required that the truck be broken into (without putting out the side window) a number of times. On another subject, I hadn't thought to look for/use coupons and will do so with certainty now.
Para.MJ: Yes, I got this rig for a song. The whole system runs fine, but the ride is like being behind the wheel of a bouncey-castle perched on top of a palm tree that is occasionally possessed by the malicious spirit of an ex-girlfriend/wife.Once that is alliviated, the rest of the project should be good times and gravy.
