Up for bid is this NOS 3-ported vacuum switch Chrysler part # J3237457. This piece fits 81-86 Cherokee, 81-88 Wrangler, 84-86 Grand Cherokee and 86 Commanche. It also fits 1980-194 AMC models w/4 or 6cylinder.  Part has AMC and correct part number molded in. You can but those repo/aftermarket switched but why would you. Over the years most of these early emission components were removed but are a must for the correct resto. Rough original box is included. Please see my other NOS and used Mopar/AMC and Jeep items.
