Seems to me only older than the 1970s trucks had copper/brass.I just looked up cores for my 77 k10 because it's never been replaced.I'll go with aluminum.It'll do.Summit only showed trucks up till 72 as best I could find.Rockauto is limited also.And besides,I hate their stupid website...unholy crap
