Switching motors in an envoy and the new motor is missing one of the alignment pins/dowels that aligns the engine and transmission. The old motor still has both. How can I remove these to put on the new motor? Is there a replacement available, if so can somebody link me? I'm working on a 2003 GMC Envoy XL with the 4.2 I-6 engine. This is all that's holding me back from having it back together so if anybody can help me to remove them I'd appreciate it!!
