  1. I have a few of those Mopar performance catalogs laying around. Being I know someone who works at a dealership ship I’ve giving him part numbers from the catalog here and there. I’d say most of the older stuff is unavailable. Sent from my iPad using Tapatalk
  2. Most of the XJ stuff will bolt on if not all. The stock lower control arm brackets have an extra reinforcement which is a little harder to cut off than an XJ. The trans crossmember has extra inner bolts on the inside of the frame rails. I don’t think that will be a problem. The MJ is a spring under. The XJ is spring over. I believe the MJ springs are longer. Sent from my iPad using Tapatalk
  3. I’ve had several early XJ’s and 3 MJ’s. There are NO CARB legal cold air intake set up’s for 87 to 90 XJ or MJ. Both MJ and XJ have the hot air pipe going from the exhaust manifold to the air cleaner box to heat air in cold weather climates. Also the top of the air cleaner housing has the vacuum thermal valve that control the hot air door. As per smog laws you can’t remove those items. Now I’ve made my own intake or used one for a 91. Smog time comes I installed the stock intake set up. Not a big deal. Sent from my iPhone using Tapatalk
  4. I went and read the emissions label on my old 88 Comanche. It doesn’t state obd at all. It has efi h20, egr, twc. So it is obd1 exempted. Sent from my iPad using Tapatalk
  5. 87 that is definitely Renix OBD1 with no dtc’s or check engine light. Sent from my iPhone using Tapatalk
  6. I don’t know what year your truck is but most likely no. The generic scanners they sell at the parts store are for obd2. That came in 96. You can find some with the adapters for some obd1. I have never found Renix Jeep. Sent from my iPad using Tapatalk
  7. 91 is when they got Chrysler OBD1. The early ones used Renix obd1 with an exemption for the check engine light and no dtc’s. They did have a double connector under the hood. There was a special scan tool that would do specific tests and then give a fault code. Sent from my iPhone using Tapatalk
  8. They are decent if you have the 1 piece axles. Most AMC 20’s have a splined taper axle. That’s the weak point. They do have a bigger ring gear than a Dana 35 and I think a 44. Sent from my iPad using Tapatalk
  9. Front is a Dana 30. Rear is an AMC model 20. Yours must be an 86! Sent from my iPad using Tapatalk
  10. The elusive 3.73 gears. All my years of working on Jeeps at the dealership and owning I have never seen 3.73 in an MJ. I’ve had people say yes I have 3.73 in my Comanche or Cherokee . I run there vin on the Chrysler VIP system and check there options list. 3.07. Sorry. My experience with both MJ and XJ 2.5 L4 and 2.8 V6= 4.10. 4.0 manual trans 3.07 gears. 4.0 automatic 3.55 gears. I’ve seen a couple of manual trans vehicles with 3.55 very rare special order. I believe the parts catalog does show 3.73 . I’d have to verify at work tomorrow. Sent from my iPad using Tapatalk
  11. Model 35. (Dana 35) should have 3.07 with a 5 speed. The tag is unreadable in the picture. Automatic trucks normally came with 3.55/3.54 Sent from my iPhone using Tapatalk
  12. Thanks picked up a set from the parts store. Only the best got my beater. Sent from my iPhone using Tapatalk
  13. Can 4x6 speakers fit on the factory rear speaker bracket. My rear speakers are mia. Wiring is there. Sent from my iPad using Tapatalk
  14. Check you vibration dampener . Make sure it didn’t slip apart Sent from my iPhone using Tapatalk
  15. The bushing are pressed in. I’ve used an air hammer to remove the old ones and made a tool using a small piece of pipe 2 flat plates with a center hole and a long nut and bolt and pressed them in. Also a ball joint press tool will work too. You can rent those. Sent from my iPhone using Tapatalk
