Who has put sparco style racing seats in their 97+ Cherokee? What all is required and do you have 4 point harnesses or 5 point?

I fabbed up my own mounts and I have 5 point harnesses but haven't built my seat belt bar to put them in yet.

Is there anyway to use the factory seat mount and bolt the seat to it? I have no clue how aftermarket seats set up... The ebay add im looking at says you need seat mounting brackets but I wasn't sure if that's for people that don't know how to utilize the factory mount?

I modified parts of mine so I would still have power seats. Depending on what year you have will determine what kind of mounts it uses and how hard it will be. XJs are offset and the seats won't be so you'll have to allow for that.
