Yea, he found what I need. It's a striker, my latch mechanism was sticking. They lubed it and it seems to have helped.
The parts he said I'd need were that striker, latch, a shim plate and a retro kit to hook the door handle wire to the latch. He said they upgraded and if I didn't need it I could return it. Total for everything's was $247. I've been sleeping on it.
