Any year yj throttle body will work, got mine from eBay and a helix spacer think I payed a total of 50 for both. Very good upgrade with the injectors an a magna flow exhaust. When you do it take out the restrictors in the air cleaner box.
I don't know what all injectors you can use mine came from a mustang. If you do a search for fuel injector swap and wade through them I remember seeing a post that had pics of all of the ones that will fit. Can't remember which thread it was been a bit ago. I'll look around and see if I ca stumble across it and link it.
