In my migraine stupor I drilled the holes in my shims larger to accommodate the the pin on my leafsprings. It wasn't until I was done that the foley of my mistake cost me a pair of shims. Since they don't come with instructions for the feeble minded(me) I didn't realize you are suppose to run the pin bolt on the springs through the shim effectively bolting it into place on the leaf springs. So now I get to wait for a new pair to arrive from summit! Stupid stupid stupid! Well I guess the dogs get that walk they've been waiting for!
