So I've just done the Koni inserts and I'm heading off to Sears for the digital level for the DIY camber gauge. I'm looking at my BGB and it says that the upper set bolt (on the steering knuckle) will allow the camber to be adjusted up to .5 degrees. There is a clear distinction between set bolts and adjusting bolts in the BGB. So I pull all four front bolts and they are identical. 14mm shoulder, 13mm shank, 13.8mm across the threads, no lobes. Are the set bolts the original bolts? Is there supposed to be a difference between the uppers and lowers? Are the upper bolt holes a little looser to accommodate some wiggle?
