@MoaByte was exactly correct. I returned to the shop this morning and Jake (House of Covers, Albuquerque) proposed we just skip the hole-drilling only option because it was just obvious that the seat foam was too high. They cut about 1-2" of foam from the bottom and drilled multiple 3/4" diameter, 1-1/2" deep holes in the center foam and narrower and deeper holes along the sides. Holes are drilled from the bottom side and a lip of original foam was kept around the perimeter base.Option #4:. Cut the foam from underneath to keep the form. Maybe some drilled holes to add comfort to the cheek and tailbone area as well.
The first try where every hole had the foam pulled out felt just a bit too soft for my 205lbs, but the height was perfect. I asked them to keep the foam in about half of the holes on the second seat and this was still firm, but the height was just about right. Now the "softer" seat (and it is barely softer...still pretty firm actually) is in the passenger side and I have a "firmer" seat for the drivers side. Both aren't as rock hard as the original SOR and are covered with 1/2" softer foam on the top.
I'm really happy with the result. Here are pictures: The first is the original SOR seat no mods, next pics of cuts from bottom and hole density for both. Last pic is the final seat after mod. My head height is 1-1/4" lower post-mod and it is a lot easier to climb into the truck. Success!
