Well just to update everyone and future 2wd guys that are interested. My spacers had to be pulled off the truck, they went about 700 -1000 miles and started getting really bad vibrations through the whole truck. What I found is the wheel was going out of balance or "moving" on the spacer. The Hub centric to the drums was perfect and no signs of movement at that location. But I have found the lugs on one side where wearing at the casting pocket of my wheel and those lugs had the chrome shipped of them. (And yes before I installed I took measurements and knew my spacers lug nuts had enough clearance to go inside the casting wheel pockets). And on the opposite side I noticed thread marks inside the lug holes of the wheels. Drove it this morning going into work without the spacers and all the vibrations are gone now. So remember buy hub centric to wheel centric spacers. Obviously mine did not work out. I may end up machining my own from steel and going hub centric to hub centric.
