well the subject says it all, but the story is i bought a front clip off a guy and am swapping out my 223t for the 4jb1t. but first, some maintenance, like new timing belt, water pump, thermostat, clutch , and rear main. i have a parts catalogue for the 4jb1 industrial engine, but the listing for the rear main comes up on the isuzu catalogue as the 2.6 rear main. is this correct? part number i have is 8-94214913-0. which was superseded, so it says online, by
8942353690. hmmm. so before i order it i was hoping to double check it. anyone?
