So to start the story I bought a 91 rio red civic for 700$ it had a d16 in it that skipped time. When purchased it came with a b20b with a bad 3rd gear and a spare trans that is good. So as I'm swapping parts the spare trans needs off the trans that was on the motor I realized the person that took the motor out of the crv just unbolted the shift linkage so they didn't have to bother with the pin. and after removing the pin I cant get that piece of the linkage off.. help with that please...

And also should I use the obd0 harness and ecu instead of the b18 ecu and the b20 harness the motor came with?
