Thanks for adding me to the Forum. I've been poking around the site for a few years now and got to working on my '49 GMC 100 this past summer. I've gotten a lot of useful information just by listening in. Wanted to add a few pics as I've come across some interesting markings and wondering if anyone knows what they are or if they're even correct. The bell housing has a blue "x" painted on the top of it, and the tranny case has white spray paint dots on it in a few places. The driveline was caked in a waxy grease that was pretty tough to get off. Under it, all was pretty well preserved. Just like someone mentioned in a previous thread , some GMC blocks are an "avocado" color. This is the case with mine. I'm uploading photos. Thanks for any input in advance.
