I have a vortec 350 that I pulled out of my 98 gmc 1 ton. The motor originally had a flexplate for the automatic, but I am wanting to put the motor into my jeep with a manual trans. I am trying to find out what flywheel I need to run, and whether or not the old style pressure plate will bolt onto the new vortec flywheel. When I called the parts store they told me there were 3 different flywheels foor the vortec motors. Any help thanks!!
