Dan, the roof rack works great and saved me the hassle of fabricating my own clamps. I just need to tweak them and I have been stalling on making my own clamps because I didn’t really want to go through the whole hassle of doing it.
It looks like I can cut the bottom of the base of the clamps about 4"s from the bottom and then cut the top off with the cross bar holders (about 3"). I would just need to make up a few support angle pieces and be good to go. I’ll also need to pick up some rectangular steel sections because the Thule cross bars will be too short because the clamps will be farther apart when shortened. But, I plan to use the old cross bars as part of a rack on my trailer. (see picture)
I picked up the Plastic carrier yesterday (nothing special but it is in good shape, solid, and waterproof and lockable). I need to figure out how to make a foldable ladder that I can use to get up there and have it stow out of the way when not in use.
I got the idea for a ladder (and because I am a massive 5’10” 178 lbs and can’t reach the top of the cruiser) while looking back at the September/October 2006 issue of 4wd Toyota Owner and Zen Dog's Cruiser (see picture) If I am going to be able to put and take stuff out of the carrier, I need to be able to get up there without too much stress or strange body positions like standing on the tire and holding onto the rack with one hand while the other hand is trying to load things because of my back. I would be asking to go straight to the vicodin playground.
If anyone has an idea about how I could make a ladder that would extend to about the tail light height and would be able to fold up flat onto the cross bars of the rack, let me know. I figure that the carrier would have to be off center towards the passenger side so I can lay the ladder flat on the driver side so I don’t have to worry about hitting my spare tire. The only thing I can think of is that it would fold like this: /\/\/\/\ with additional support arms (with rubber pads) against the metal of the top, body, and rear tire carrier.
I also attached a picture of the trailer for you Dan and earlier quips about it from you

It will have the roof rack from the picture at the top of the thread, minus the lights of course. The roof rack will be mounted above the carrier on the trailer in the picture for additional gear that is light and easy to lift and for my awning to attach to. The vertical supports will be able to fold up on one side (like the Heep roof racks with a soft top) so I can get into the carrier and I do not want the rack so high that it kills my COG on the trailer.
I really need to get back to work now . . .
