Holley 1920 diaphram return spring

Well, so far I've found (3)BBD's, (4)BBS's, & (1)1920, and it's not a match to Yours...............but here are the numbers.........
6594 1373
3698347
it has an external bowl vent tube for canister equipped vehicles. I've had at least the one from My '69 Dart, the one from a '70 Valiant 4dr. I parted out, the one from My
'72 Swinger that got the built six from the '69, & the one currently on the '72 Duster. Plus I believe the orig. set-up from another eng. project I purchased from somebody
w/a header etc.. crap.....I'll check the one on the Duster after work tomorrow. I'm known for not throwing away anything pretty much, but for now..............:rolleyes:.......
UPDATE;
OK, the one on the Duster looks just like the other on equip/feature wise, but is a
different list#....................
