I don't know the exact reason behind the angled mount, but I would say it was likely for clearance for the I6 air cleaner assembly. The trucks in the '67-'72 era with the I6's and power brakes, used an offset air cleaner. If you use this booster bracket in a truck with an I6, you can not use a centered stock style air cleaner. There is plenty of room for a straight mounted booster and a big block in these trucks.

Please educate me on this point.
