You can install a stock flywheel and have a shop balance it. I can't promise the prices will be happy, though. I did catch the external part, which is actually what had me stumped. If it was external, you'd have to go in to get it balanced anyway, so why not make them show you what would work? Thus my confusion. Again, depends on the type of bell housing, depends on the type of clutch you get as to whether or not it has to be "pull." In simplest terms, the only thing that affects your choice of anything based on your transmission is: A) Input shaft - spline count, shaft length, shaft diameter. These things determine the clutch type. B) Bolt pattern. What bell housing will hook up to it and your engine. The bell housing is the adapter between the bolt patterns on the tranny and engine. Tranny is universally the same, so one half of the bell housing is always the T-56 pattern. The other half adapts between different motors, aka Dodge, Aston Martin, Holden, GM, etc. And - this is where I'm reaching - it should bolt pretty much universally to GM V8's. Breakdown: Clutch, you'll want a 26-spline with whatever diameter yours is. 1 1/8", I'm gonna guess. Here are a couple of clutches: http://www.keislerauto.com/index.php?/450-ft-lb-high-perf-11-borgbeck/sachs-clutch-kit.html http://www.keislerauto.com/index.php?/vmchk/350-ft-lb-high-perf-10.5-borgbeck/sachs-clutch-kit.html If you take Droptop70's advice, then the second link will be the one for you. The first link is to a 168, then second is a 153-tooth, the one he suggested. No need to do that no matter what happens. If we didn't make it clear enough to understand, then what good are we doing anyway? Really sorry this got so complicated and confusing! Let me know if I missed answering anything. I've spent a couple hours on this. Mostly just looking up illustrations, diagrams, materials and links for you, even though I didn't end up posting them.
