Topic: Help with correct distributor and single/dual vacuum advance?

[jeff8877]

Hi guys,

Been trying to figure out what the correct part number is for my car and whether it had single or dual vacuum advance. I THINK the part number is D3ZF-12127-GA...can someone verify? But I have NO idea if it had single or dual advance and can't find definitive answer anywhere?
