i have a brand new never installed american powertrain 130 tooth 10 1/2" flywheel part number FWCH-10004CS it a special made flywheel and has the windows in it so you can run the stock crank trigger on you A833 4 speed transmission. it is externally balanced for a Magnum 360. it weighs approximately 28lbs not sure if american powertrain still has these available. maybe they will special order custom make one for you now. but this one is still brand new and cheaper to buy with no wait time...
