I just purchased the tach conversion set up for my 71 c-10 pick up. But the directions said the new repro tach is not compatible with an HEI distributor which my truck has (late 70,s gm style). Do I need to put a points distributor back in or what? Please let me know as I want to complete this project now that I have my new parts! Thank you.
