    If you originally had a 4 speed then you will definitely need a custom cross member. If you had a 5spd then I think you can get away with the original member - someone will confirm if this is correct.

    Clutch is only may Need to mod the fixingpoint, if thickness on flywheel and clutch us difrent. This you check with put IT on and ser when realease bearing hit the clutch, when arm is as long back in the hole as possible. Crismember Need to be modded i think, since t9 and mt75 is not familier, but no big Job.

    okay. then if you have from 4cyl Sierra, and dont do the 4x4 cossy front house(no need to do this, if absolutly dont need starter on oposite side, and run 4x4 starter). then you need to weld on a extra 1,5cm on the fixingpoint ball thing, for the arm. grind allitle inside the house(if dont bother, it will be some noice at first run, but will grind itself), so have free Space for the cosworth flywheel, and chop out a bit, for oildrainplug if cossy 2wd sump. and need to find out what starter motor i used...

    I replaced the type 9 gearbox with a MT75 in my Sierra, most 2.8's with a Type 9 box use a 3 bolt starter motor but the MT75 uses a 2 bolt starter motor.
    You can use the 2.8 flywheel and clutch with the MT75 BUT you have to make an adjustable pivot point for the release arm to take up the difference in flywheel thickness between the 2.8 and the 2.9.
    The release arms are different on a type 9 box and a MT75 box
    If you're after a more straight bolt in conversion then use the 2.9 flywheel and clutch.
    My MT75 just bolted up to the type 9 cross member but yours being a hybrid I'm not sure.
    Also drive shaft needs to be modified to take the MT75
