e performed. The locations indicated with yellow lines will be beveledonly on the side of the plates that the lines lie on. The location indicated with the red line should be beveled equally on both sidesof the plate as welding access is available on both sides of the plate.Image 3- Passenger’s SideImage 4- Driver’s Side21. Re-attach the supplied brackets to the stock frame brackets and push them out against the frame rails while the bolts aretightened to about 18 ft. lbs.22. Attach a Hooker Blackheart BHS514 Hemi clamshell cage and 71221016HKR (black)/71221017HKR (red) poly insert to bothsides of the engine per the instructions included with those products. If you are installing a 2003-2008 5.7L Hemi truck engine,ensure that the engine oil dipstick is installed in its stock position on the engine block.23. Using an engine hoist, lift the engine and lower it down into the Hooker Blackheart engine mounting brackets and couple themtogether using the bolts and nuts from the Hooker Blackheart 71223015HKR hardware kit. The nuts should be installed on thebolts for safety, but do not need to be fully tightened at this time.24. Support the rear of the engine with a screw jack or other load holding device and remove the engine hoist from the engine.3

25. Install the transmission and transfer case adapter to be used into the vehicle (not the transfer case at this time) and attach themto the stock 1997-2002 Jeep Wrangler skid plate using the Hooker Blackheart BHS521 mount adapter. The mount adapter canalso be used on the stock 2003-2006 Wrangler skid plate by making custom 1” spacers and the stock Jeep Wranglertransmission mount. Once attached, bolt the stock skid plate to the frame with the stock skid plate bolts. You can also use anaftermarket crossmember of your choice, as long as it replicates the factory engine/transmission offset amount towards thepassenger’s side of the vehicle. The powertrain inclination angle achieved in this step is a reference point that can be modified tosuit the needs of a specific build type (i.e. using a transfer case drop for adjusting U-joint working angles, or reducing the engineinclination angle to assemble the vehicle in a belly tuck/double cardan joint equipped driveshaft configuration).26. Visually inspect the position of the supplied engine mounting brackets a final time to confirm they are still bearing up against theframe rail. If not, slightly loosen their attaching bolts, one at a time, and force the brackets outward against the frame by wedginga pry bar between the engine mount cages and the mounting brackets. Hold each bracket against the frame and tighten theattaching bolt to hold it in place.27. With the drive train installed at the inclination angle you intend it to be used in, tack weld the engine mounting brackets in placeon the frame and then remove the engine, transmission, and transfer case adapter from the vehicle once more.28. Weld the engine mounting brackets to the frame at the locations shown in image 5 below for the passenger’s side bracket, andimage 6 below for the driver’s side bracket. As prescribed for the beveling in step 20, the weld locations indicated with yellowlines should be welded only on the side of the plate the lines lie on. The locations indicated with red lines should be welded onboth sides of the plates since there is access to do so. You may increase the number of welds beyond this point, or fully weldthem, as you so choose.Image 5 - Minimum Weld Locations for the Passenger’s Side Engine Mounting BracketImage 6 - Minimum Weld Locations for The Driver’s Side Engine Mounting Bracket29. Once the frame/welds have cooled, paint the engine brackets and surrounding frame areas with a paint coating of your choice.30. Re-install the engine, transmission, and transfer case adapter in their previous positions and fully tighten all their attachingbolts/nuts. If you are performing a no-body-lift installation and haven’t already done so, you need to remove a portion of the lipfrom the air bag module gusse
