I came across a thread mentioning the V5M21 being an upgrade to the KM-145 so long as the bell housings are from the 2.4 4cyl and not the 3.0 V6. so i thought i would ask to make sure, are the bell housings removable on these? I know next to nothing about the post 89' pickups and i know both my KM-145's are a one piece deal. I was browsing craigslist and found a 94' MM 4x4 with the V6 and i know i could get the bell housing from a 2.4 2wd (if they are removable) but i would like to be sure before making an offer on it. are there any other things im overlooking with this like the mounting, yokes, or wiring. should I forget about it and just rebuild my KM-145
