what came in a particular vehicle will be determined not by what car but the distributor number itself. ford parts and service denoted all replacement parts for distributors, by the number on the housing. so to even look up a spring or and internal its listed by that number in the parts books.
if your looking for a distributor to be done for your particular build, i would hand it off to someone with all the info and the parts and a distributor machine to set it up. you can list the particulars of your car....including engine trans etc...and this guy will do a unit for you...
