I did a lot of searching for a front bar for my one ton panel a couple of years ago. The 1 ton and 3/4 ton front frames are the same, I think. Anyway, I ended up buying a heavy 1/2 ton sway bar from Patrick's. The only adaptation I had to work with was to make new plates for attaching the ends of the bar at the spring plates. It has worked very well and really did help the driving control.
