Innovative new design Dirty Dingo modular cross member for installing the LS Gen 3 and Gen 4 engines into 1967-72 Chevrolet and GMC 4X4 trucks. This is a true "bolt in" design. Precision laser cut from 1/4 plate steel. Surface sanded on both sides and folded with a large radius on a CNC press brake. Easy to install with a hand drill and a 3/8 drill bit. Designed with hidden slotted adjustable plates to accommodate out of square or bent frame rails. Utilizes updated captured clam shell style frame mounts while retaining factory position of engine mounts. Center section easily unbolts and drops out for oil pan removal. Includes outer frame plates for added strength. Billet aluminum center spacers are machined from 6061-T6 aluminum. All hardware is grade 8 zinc coated with super 9 double thick washers. Does not require a lift kit to install properly.

Gen III/IV engines will require using a Holley 302-1 oil pan.
