Are HEI cap & rotor available with brass contacts? (I assume they are better/last longer than contacts that appear to be aluminum.) If not aftermarket, maybe OEM parts. I hate to bother with a minor question, but I don't have a dealer nearby, and figured this would be an easy one for you guys!
FWIW, I bought my GM HEI used in '86, and don't know what it came off of.
