    Which "Center Support Bearing" for "early model" E30 w/ M54 swap? (two options)

    Hey everyone, I am trying to figure out which CSB to use for my swap into my 10/86 325es that is getting an M54B30 w/ ZHP 6spd.

    The E30 changed its DriveShaft in late 87, and the CSB along with it, so there are two CSB options, an early and a late model, but I don't know if the CSB corresponds to the early/late BODY or the early/late DS. I am half guessing the body/mount-point did not change, and it corresponds to the DS change, so that would mean I want the late model CSB to work with the E36 DS, but that is just a guess.

    I already figured out the front section from a Z4 M/S54 6spd Manual and the rear section from an E36 M3 Automatic (or a number of E36 Automatics), but I am struggling to find clarity on which E30 CSB to use. If I was putting this into an 88+, this would be no problem, because I would use a "late model" CSB, but everywhere I look everyone just says "use an E30 CSB", not which combo of early/late etc...

    Help/Guidance with this would be greatly appreciated!

    The body changed. So you'd want the early support bearing. If you haven't already figured it out...
