JEGS solid transmission mount is designed to replace the soft rubber original equipment mount in racing applications. Reduces engine twist (when used in conjunction with solid motor mounts, mid or front motor plate) and transmits more power to the rear tires. Fits one and two bolt transmission crossmembers in most RWD Powerglide, TH350, TH400, Borg-Warner, Muncie, Saginaw, Chrysler 4-speed and Richmond 5-speed equipped vehicles. Features slotted top (transmission) mounting holes for adjustability and three bottom (crossmember) mounting holes for one or two bolt crossmembers. Includes 7/16"-14 bolts and washers. Made in USA.
