Hey everyone, new to the forum and did a little searching around and like everywhere else I have tried there is little to no info to answer my questions. So the issue is I have a 1972 D200 quad/crew cab (full 4 door), with a ‘73 360la swapped in. I was able to decipher that it was originally a 318 truck. But the problem comes in that it is an old retired Air Force truck, so the vin after the first few normal digits makes no sense on what I have found, and since it is a Factory d series truck not a w series or power wagon there isn’t a whole lot of info out there that I can find. I want to do a basic maintenance and overhaul, but I am having trouble how to figure out what exactly I have under the truck, when I try to look up anything (I.e. brakes, wheel bearings, front end pieces, ball joints, rear end pieces, etc.) there are like 3 different drum brake sizes, 2 or 3 different front ends, etc. and trying to figure out what I have is hitting a brick wall. Any help would be great. I can try to post pics of the military data/spec tags later if that may help or if someone can point me in the right direction of a data base or search engine I would greatly appreciate any help I can get. I love the truck and really can’t wait to get it back on the road and ensure it will be safe to take out the kids and dogs.

Thanks in advance
