Ok, thanks, found them at Advanced Autoparts online for Ford.
Searched under a 1979 Ford Mustang 302.
Price for the Vacuum Advance Canister for a DuraSpark Dizzy is
pretty much the same as, or MORE than a complete Distributor for a '79 Waggy !
Vacuum Advance Cans are from $42 to $69 plus tax !
A complete new '79 Jeep Dizzy is $50 with a $50 core charge.
What a joke 🙁:
The old DuraSpark I have is missing the vac can and drive gear.
Wonder if that matters if it can be used as a core ?
Anybody got an old DuraSpark for parts ?
All I'm looking for is a vac adv can to make this spare complete.
But shipping cost will probably make it cost too much.
Even the cost to go junk yard searching is high with the price of gas.
