    The engine it goes on is not the real factor. Your matching the diameter, spline count with size, and thickness. The thickness and diameter is the same as what a 225 clutch is, while the spline count and size matches what a T18 input takes. There used to be a Dial-A-Clutch site that let you put this in as factors and it would show you PPlates and discs that matched what you needed.

    the key here is match all your parts with the replacement ones
    Pressure Plate height and number of springs(9) Borg&Beck
    clutch disc disc diameter /spline count /shaft diameter
    throw out bearing height / bearing for 3 finger or diaphragm type

    Ah I see now that I will need the same clutch you have spec'd for your Jeep because of my T18 swap. To be clear you used the clutch disk and pressure plate from the kit and then what throw out bearing?

    Ron: Thanks for clarifying what I've been saying less elegantly: While other guys have no doubt successfully used X, Y or Z, and while my Jeep may not even have the clutch parts it "should" have, I'm not knowledgeable or experienced enough to be juggling and compensating! I've really just wanted to positively ID and replicate my existing parts: I need everything going in to match the pieces that came out!

    (I think I'm there, by the way. Just waiting for a couple of deliveries.)

    I didn't mark down the part number for the TO - notes indicate stock Buick TO. You may want to look at the one from Novak that is adjustable. I would also recommend a full read on there about clutches.

    Other items to note - my input bearing retainer was turned down to match GM specs (also helps with 'which TO to use'). I used a Chevy Fork with my hydro setup as well. I believe its the whole combination that helped make the pedal as soft and smooth as it is.

    I don't imagine it will take very long, either.

    UP AND RUNNING
    I'm tardy in posting this (work, travel, etc.), but ol' 46ODDFIRE is up and running again. Here's a thank you to the collective wisdom on this forum, especially you, Ron, for riding over to give my Jeep an up-close-and-personal look. I also had help from a couple of neighbors at key points of disassembly and reassembly. As noted before, I'm a middling mechanic at best, so your input was valuable.
    A few thoughts that might be of use to other first-time transmission droppers:
    -- I went S-L-O-W-L-Y and deliberately. I used penetrating oil on recalcitrant bolts, and I actually gave it enough time to work. I bought a small-parts organizer box and grouped all the bolts and washers in their own, clearly labeled, compartments. I constantly asked myself if I was forgetting something. I was so afraid I would miss some key step that I typed my own step-by-step re-assembly instructions and kept them under the Jeep with me.
    -- The transmission/transfer case/overdrive is heavy, lumpy, and weirdly balanced. Where is the center of gravity on that thing? My brand-new transmission jack -- the scissor-lift kind -- could not hold it level, even with lots of strategically placed blocks of wood and the tie-down strap. When I wasn't moving it, I used a board as sort of a crutch to help support the transfer case.
    -- I cleaned everything and painted everything that could be painted. As noted on this thread, that purdy paint won't look good for long, but there is something satisfying about giving everything this sort of care and feeding.
    -- I now consider those YouTube videos of people dropping transmission-bellhousing assemblies from stock flatties to be quaint reminders of simpler times. It's harder to remove, and squeeze back in, a larger-than-stock bellhousing and transmission. A new transmission mount made it all that much tighter.
    -- I used (temporarily) long transmission-to-bellhousing bolts. Once we had had one connected, we had a pivot point for lifting and rotating the transmission to line up a second set of holes. Numbers three and four were easier. With everything thus in alignment, it was just a matter of sliding the transmission forward. This took a couple of tries. I used a long rod stuck through the bellhousing window to turn the shaft ever so slightly, and then everything slid into place nicely.
    -- On the first test drive, I heard a funny sound at about 10 mph. Back to the garage. I crawled underneath and just stared at everything until I saw that I hadn't tightened one of the universal-joint U-bolts all the way down. Yikes!
    -- Between this repair and last year's repair of the clutch linkage, I have installed and removed throwout bearing forks many times. My observation: Not all forks are created equal. I may do a separate post on this subject.
    -- I am now leaking oil from the front of my rear differential. It's not gushing, but it's worse than before. I am trying to remain calm. This may an example of something I should have left caked in oily crud, because that crud was probably working as a leak block.

    But: It sure is great to be driving it again, even if I'm putting around town.

    Just a note - the organization item I use the most in the shop is a box of quart and gallon size Ziploc bags and sharpie. I then put all project items together in totes I have if it gets put off for a while... tape with labels help those getting older with memory items. Also, I hope you bought a composition book to start writing all these new adventures down in. Dates, sources, and part numbers come in handy in the future :bananatool:
