Tri-5 Conversion mount kit for installing a SBC or BBC into a 1955, 1956, or 1957 Chevy Bel Air, 150, 210, Nomad or Wagon from stock front mounts to side mounts. Will allow you to install a Gen 3 or Gen 4 LS engine with our LS Conversion Motor mounts. These will work with seamed or seamless California frames. These mounts will provide a much stronger mount support over the original style stock front mounts.  This kit is a bolt in kit and will require the removal of factory rivets and drill 4 new holes into cross member. When using with a small block engine these mounts will move the engine forward 3/4" for HEI clearance. Mounts are laser cut and CNC folded from 3/16 steel. Includes the correct 3 bolt rubber engine mounts and all necessary grade-8 hardware to install on frame.
