D, I use 3" x 2" x .188" wall. I'm in for the night, but will take some pics of the spindle welds for you. I cut the 1.5" hole in the shell and weld both sides of the spindle penetration. I grind the "outside" weld flush with the shell and leave the "inside" weld as is. Then when you know your angle of the bumper, you can cut the spindle down and just weld it to the cap or shell on the "inside" as well.
I'll shoot you a pic tomorrow.
GO AMERICAN LEAGUE!!
