Well, where do I begin? I have a 92 Dakota w/ auto tranny. I am switching to a manual tranny. I have a NV3500 ready to be installed but I ran into a problem. I bought a flywheel for a 92 dakota manual w/ 143 teeth, and a clutch 2 match. When we tried to install it it was too big. The holes all match but it was too big in diameter like it was hanging off the sides of the back of the motor. The flywheel looks like a really tight fit into to tranny too. The flywheel for the NV3500 is the same size that I have already. The guys at Autozone werent too sure what to do(go figure) so we looked up a 91 model and the flywheel has like 133 teeth so its prolly smaller. Are the blocks the same? Will the 91 flywheel/clutch mesh w/ the NV3500. Someone who has done this swap will be very useful. Also, will I need a new sensor for the flywheel.
