I had a question about this bolt size.
I'm going to be removing my emissions "stuff" since my '75 does not have to
go through emissions anymore (>=25 years old vehicles are exempt in CT.) My
question is what size bolts can I use to plug the injection ports, are they
pipe threads, or straight threads?
I know nobody out there would dare remove their emissions stuff ;-) but
maybe someone could tell me the thread size "in theory."
Thanks in advance!
