are those 18's? 275/70/18 would be about 33.5 and fit on there nicely. Here is a chart to help you decode the metric sizes... your ideal width will depend on your wheel width. Tire Tech Information - Diameter Comparison of Light Truck Tire Sizes

I think 275/65R18's came on the ford factory 18's. Thats about 32.5 Not a whole lot bigger than stock 16" ex wheels.

 

Assuming the kit is correct for the truck, castor is returned through the radius arms in the second pic. Camber is returned through a bracket (not shown) where the split axles meet near the front of the engine. There should also be longer sway bar end links and a longer pitman arm - hard to tell from the pics.

 

I took some more pictures today while I was changing the wheels:







I also got an estimate for the repairs needed to eliminate the Death Wobble (DW). According to the local shop, I need upper and lower ball joints, inner and outer tie rods, and a new steering stabilizer/damper.

I am replacing the ball joints and tie rods tomorrow. Will wait on the steering stabilizer.
