Can anyone tell me the exact way to replace the OPDA with a new unit. I know how to mark the old one in order to reinstall it but I'm replacing it with a new one. If you leave the factory pin in place until it is installed, do you still have to find TDC on #1 plug and check the timing mark or can you just stick it in, bolt it down, remove the factory pin and start the jeep???
