New Mazda Owner

New guy here from Kentucky. I remember hearing about this site a long time ago from Slammed83mazda, just never had a reason to get on here til now. Well, I got my first B-series a couple weeks ago. Always been a fan of the 86-93 body style, especially bagged extended cabs with 4x4 sheet metal. Anyway, I have a '68 chevy truck for a project and just bought my first house last year so I wanted a cheap truck I could daily drive. I looked for close to 2 months at Mazdas, Toyotas and Hardbodys, but couldn't find anything nice and for the right price. I finally ended up with this. It's a '93 B2600i 4x4 5 speed with 155k miles. Body is in pretty good shape other than a small surface rust spot forming behind each rear wheel the core support has quite a bit of surface rust. Also, someone painted the top half with spray paint or some type of bedliner, I'm really not sure. Doesn't look too bad, but eventually I'll change it. The frame looks good so far from what I've found, I probably will do some sort of undercoating before too long. Interior is good other than the drivers side seat being a little worn and black tape on the top of both door panels. Biggest issues with the truck are that the 4wd does not currently work(previous owner said a switch in the transfer case, i haven't had time to diagnose and try to fix it myself yet), and the A/C doesn't work(all there but I think the compressor needs replaced). Two of a long list of things I plan on researching on this site. These are the only two pics I have right now...
