This manufacturer has made the unit with 2-horizontal slots on each of the belly pan sides, to place over the 2-lower rear cowl bolts. This requires complete removal of the 2-cowl nuts in order to get the sides of the belly pan horizontal slot over the cowl bolts. This can only be accomplished after removal of the 2-cowl nuts and pulling out the lower rear cowl off the bolts. Other manufacturers have a vertical slot that enables pushing the sides of the belly pan over the 2-lower cowl bolts and thus the nuts are not completely removed. In my installation effort, after removing the two nuts and pulling the lower cowl off the bolts, I was able to get the front lower cowl bolt hole back on the bolt, but not the rear one. It would not line up no matter how much tugging and pulling I tried. To facilitate a simpler installation I ultimately used a metal grinder to make a vertical slot into the original horizontal slot, as done by other manufacturers, so I could slide the pan sides directly over the 2-bolts. After numerous attempts to get the rear cowl bolt hole back over the rear bolt I finally had to jury rig a ratchet come-along between the front hole and the rear saddle guard, to pull the lower cowl rear ward to match the bolt with the lower cowl mounting hole. To simplify the installation grind a vertical slot into the manufacturers horizontal slot and only loosen the lower cowl nuts. Absolutely do not remove the nuts.
