Yeah, thanks that'd be great. Whenever you can, no rush!
My front mount is just behind the body mount. Leg is 2x2 square tubing and is 10.75" long, then it was cut at 80° to match the angle of the frame up front. I have s***ty tools though someone else could probably get a more precise angle, but 80° worked for me.
Rear mount is just behind body mount and is 6.875" long. It has to go under a brake line there so I added some rubber hose to prevent rubbing.
Mount is 7 13/16" by 2.75" and 1/4" thick. The 7 13/16" height puts it pretty close to the body pan up front, but it's still pretty tight to allow room for the 1/2" bolts. I need to do a little grinding to get some clearance there. If you went with 3/8" or 7/16" bolts you could get some more room, but you probably want the strength.
Passenger side mounts are the same lengths, and nearly the same locations. Front location is the same, rear location is maybe ever so slightly forward. It's tough getting the bolt in because of a heat shield up top. I had to bend it down to make it work. The middle leg can go just in front of the rear body mount on the passenger side. I didn't add that one because I was in a bit of a rush, and the first try didn't fit right so I gave up. I have 2 mounts on each side.
Gussets are 1/4" , I got a little to quick and warped my mounts a bit welding them in.
Those leg lengths put the main rail just outside the body seam, maybe a 3/16" outboard of it. Then my outriggers are 1 7/8" pipe.
As for how low to mount the legs to the frame mounts....I kind of eyeballed it and basically put them as close as I could to the bolt heads and still be able to turn them. They are just under an inch above the bottom of the frame mounts, maybe 15/16" from the lower edge and that gave me about 1/4" of clearance off the rocker panels
