Thanks to those of you who posted the spindles for the tire carriers! Helps a lot with the rear bumper! I was hoping to find parts for the front bumper too, such as the nice heavy duty hoop mounts like those on the ARB bumpers and mounting plates for a winch. I'm sure some of this I could fab up myself, but I do have a metal shop with plenty of steel. No CNC machine though.
Also, this bumper won't be the typical angled, boxy shape. I'm looking to make the bumper follow the contours of the body. I'm fortunate enough to work with a good fabricator and a shop with plenty of tools to make it happen.
