Choopi, Glad you're here. The 82 and 14x4 are perfect for it. As far as the LG collapsing are you saying the block has come out? If so that's a common problem with them but very easy to fix. A good fix for it is to take the LG off and drill a couple of holes for some metal pins that will go from the surface that the LG goes on down through at an angle and come out of the plywood section that is where the belly pan butts up against. It basically pins the LG block to the plywood bulkhead behind it. Let us know how you come out with it.
here is a pic of what Rob just said
maybe it will help, we have all had that problem i think[:@]
make sure you use some 30 min epoxy down the holes after you drill and just before you screw in the screws. i usede 8-32 allthread rod on the first and on the second i used a couple of 6-32 screws about 3 in long.
