Just wanted to write this for anyone needing a fixed or replacement airbag module. I called up airbagsystems to tell them the codes that I got when I got them read... Chris looked through everything, said there was no common parts other than the airbag module itself, and said he would send another replacement module as soon as he could. He kept in touch over the month saying he was looking and told me when he did actually find one, programmed it for my truck like the other, and sent it out... worked like a champ.

so airbagsystems does in fact work, they know what they're doing, and were willing to rectify the issue I had.
Very reputable company who stood behind their product. I am very happy with their customer service and even happier they fixed an issue for $100 when it would cost over $500 at the dealership.
Wanted to write this for anyone considering getting their module fixed or replaced by them... I highly recommend
