Searched all through here, but no answer.
My YJ is a rebuilt title supposedly with a rebuilt motor swapped in during or after the rebuild/retitle process so the VIN has no relevance to much of what is actually in the Jeep. Although everything appears late 89: AX15 transmission; exhaust manifold has the date 8 11 89 on it. (And no cracks! Yet.)
Playing around with some online parts lookups, either Autozone or Advance Auto (can't recall) had a notation that 20% of 89 YJs had a M code engine and the other 80% the T code.
Does anyone know for sure what the differences are? I've read all the speculations about which models had V-belts and which had serpentine - sounds like late 80s Wranglers were "parts bin" built as parts stocks were used up during changeover periods.
So, anyone have good info?
