Okay, have a rebuilt nv3550 tranny to replace the AX5. Now what i need to know is how the input shaft enters the engine. Do the spindles go into the motor or does just the round tip just enter alone and the clutch disk turns the tranny. If the spindles do go in what kind of flywheel would i need because it will not fit over them. I could possibly get it drilled out by our local machine shop.
