Just an FYI for everyone. My original reply was to purchase a 22301-P7901 Vacuum Canister was for the OP, who noted that he needed to buy a new one for his ZX dizzy. 22301-P7901is an excellent choice, being both a reasonable price and being a Canadian spec model with a single line. However, you do not need to buy one if you want a Vac Can that is adjustable. EVERY Datsun/Nissan electronic distributor that has the " Putty " blob on the end is fully adjustable for travel and spring tension. Both 6 cylinder dizzy's and 4 cylinder dizzy's. A really cool feature...
