When installing the LC349975 rear bracket, should I drill through all of the 4 predrilled holes on the bottom horizontal plate of the bracket into the horizontal bottom steel part of the 10 inch frame I-beam? This would result in drilling two holes into each side of the flat horizontal part of the I-beam for a total of 4 drilled holes. Is this the correct installation for the lower portion of this bracket to the trailer frame I-beam in order to assure that the rear jack leg when retracted will stay vertical? Thanks for a reply.

On that horizontal plate, the install instructions only call for two bolts to be used. So if you already have two existing holes in the underside of the frame, you won't need to drill additional holes.

@ChrisR The instructions call out for the holes in the underside of the frame to only use 2 holes and wording is "The two holes chosen MUST be directly across from each other." This confuses me. It either means chose 2 holes so that the bolts are on the same side of the I ( as in "I" beam) or they are saying 2 bolts (close together) at one end or the other. I think they mean use 2 holes that place both bolts on the same side of the "I". Can you confirm the right answer?

You will want to use the bolt holes that are on the same side of the I-Beam. If you check out the attached installation video you can see our installer pointing this out if you start at the 3:58 minute mark.
