IF INTERESTED, please email me directly thank you! Paypal or US Postal Money Order only. sfaboston (AT) hotmail.com I am told and as far as I have read, these came on Big Block Mopar Dodge Plymouth Chrysler 383 413 426 440's. This is used, NOT NEW, NOT NOS. The guy I got it from said it ran great and had low miles. It does seem to open and close nice and still has its factory sheen. Not all corroded or gummed up. Likely will need tuning for your application etc. Looks to be in good physical shape. Be great on an early Gasser or period built car. $115 shipped in lower 48
