    Dan had asked me to look up my old Centerforce I clutch info for my T18 swap. I thought I'd post the info I provided to him via PM so we can save it for posterity and it is available to our Search.
    My swap was done in 1995 by a local shop. Here is the info I sent to Dan:
    *********************
    Here is the info, as best I can interpret it.
    First, some background. My tranny is a Jeep T18-B. Had a long input shaft, from a full-sized rig. The shop swapped that out for the Ford 6.5" shaft, looks like p/n MTG 13-01-085-011. That took the input size down to 1 1/16, 10-spline. (The Jeep shaft was 1 1/8-10).

    They do not show what pilot bushing they used.

    They also show a "used main drive gear" on my invoice. I suspect that is the bull gear and not part of the tranny.

    Advance Adapter kit, Jeep T18 to chevy, p/n 712528. Current price ~$273.

    Clutch disc:
    Centerforce p/n 381021. Current price ~$100 (per the CF website)

    Pressure Plate:
    Centerforce p/n CF 360056. Current price ~$199

    The throw out bearing is p/n BCA 614018 (some scribble on the invoice, it could be 64018 ) Old price was ~$27.

    They gave me a used clutch fork, I guess the one from the T14 wouldn't work. Not sure what p/n. Looks like they were going to install clutch fork p/n GMC 15687296 and advance adapter pivot adjuster 716184C, but it is crossed out on my invoice. I guess they found a used set up that would work.
    They installed good used parts where possible to save me some $$.

    I used a pre-1971 bellhousing, with the separate T14 adapter removed.

    They found a used front and rear drive shaft that worked without cutting. I don't know what configuration they came from, I suspect a later model. Once your tranny is in, maybe you could measure your driveshaft needs and try to find a good used set to save a bit.
    ******************************************

    If anyone has any questions let me know, I'll try to answer.

    HTH!!

    Hey Lynn, that pressure plate number doesnt come up on the centerforce website.

    The 225 centrforce I number is CF361662

    I am not sure though, i found the Centerforce II pressure plate number CFT361874, I wonder if the 231 pressure plate will bolt to the 225 flywheel?? I am using the 225 heavy flywheel on my 4.1L buick motor. Does anyone know bout that???

    It's there... but doesn't show up through the normal "select your vehicle" application.
    Use their search feature, plug in the p/n. It'll come up, but doesn't show the 225 as an application...

    HHHMMMM I stil cant find it by doing a search. Do you run just the Centerforce I pressure plate??

    I think i am going to start another post bout this. I found everything else i need, i just need to decide to use a 225 pressure plate or go for the 231 pressure plate where i can get the Centerforce II.

    thansk!!!

    Lynn,
    The main drive gear is another term for input gear or input shaft. Should be the ford input that was used. Pilot bushing is a standard GM to Ford conversion. You can take a Chev pilot bushing and machine the inside to fit the Ford input pilot, or buy one already done from AA, Novak, Jeg's, Summit, R&P, and many other sources. :D Nickmil.
