I have a 1978 350 and the ballast resistor fell apart. So old I cannot read part #. Anyone know the OHM or correct part #?
When you say you have a 1978 350, do you mean Crusader model CH350 (454 cubic inch) or 350 cubic inch (Crusader model CH270)? If it's the latter, the Crusader part number looks to be 41064. https://www.marinepartssource.com/crusaderpb/220ap73.asp
Hope that helps.
