well,it seems that the aftermarket has thought it wise to stop making wiresets for anything GM made before 86.if you have the small cap HEI youre good to go HOWEVER if you,like me,have the large cap HEI and you wish to keep the ring on top of the dist. that holds the wires you,my friend are out of luck. i went to pep boys,autozone,advance,oreilleys and even the dealership looking for a correct wireset....no luck.so off to our local NAPA warehouse i go .they had a set that was close and they had another set that was also close.i ended up buying two sets in order to have all 8 wires with the correct terminals. i will post the part numbers shortly

 

BOSCH Part # 09685

 

acdelco 618N gm 12043815 if the top boot does not have the nipples they will still positively lock onto the cap terminals, most of the time the holders get throw away because the a pita.
