Shop said I need a new computer - 99 TJ 4.0L

Okay this is a long story but please help. My Jeep is a 99 TJ which was an SE that was swapped to a 4.0L with an AX-15 5 speed transmission. As far as I know, the motor is from a 2001 wrangler, and the computer it has is off of a 2000 wrangler. I've been having intermittent/steady CEL's for the front/rear oxygen sensors (I have 4 total which are post 2000 setup) and took it to a shop that took an entire 3 weeks to basically only rewire and put new sensors on the rear and put on new connectors to NOT fix the problem and then tell me the computer was most likely the issue and would fix the CEL for good.

Since it was already 3 weeks I took my truck back while they were "ordering" and waiting for a computer to come in for two more weeks so I just called back today inquiring about the situation and he tells me that he's been meaning to call me etc etc and that i can drop it Friday to him and he would have it ready by Monday afternoon for $350ish. I'm obviously fed up with this shop though I cannot describe how frustratingly poor their communication is (over 5 weeks they have called me 1 time regarding my car, the other times I always had to call)

I know I cant really order a computer from one of the places online because they only program by VIN which clearly will not work for me since I have an engine swap and a mismatching computer as well. I would really like to avoid this shop and once this is all done I will write them a scathing review online - but I really need this fixed as I cant get my truck inspected until I get this fixed - and further even tho I cant stand this shop they claim to "know" the issue so I dont know if i can just bring it to another shop and say hey pick up where these guys left off and expect them to go the same route or be able to rely on second hand diagnosis.
