Vacuum advance identify

Thank you mderoy340!

I was initially suspicious ordering the vac advance not knowing the year of distributor & obviously I was in err!!

Upon further examination of pics on Napa's site, the '70 year model looks correct!

On Napa's site, they show to have two listings and reference to a # on the dizzy for correct application but all evidence is gone, any insight as to what the difference is..?
