I just "Googled" "Distributor for '58 Studebaker 259 engine". even though there were no HEI's listed for Studebaker,all the regular "dizzy" parts came back as AC Delco. You may be able to cross-reference your "Dizzy",to a compatible HEI unit. Check with your local F.L.A.P.S.,or follow previous suggestions,from H.R. L. Jerry knows his stuff!
