When looking at the 1967 Pontiac Service Manual, it implies that shims are only used on automatic equipped cars. So when I converted my TH400 automatic car to a 4 speed; I omitted the shims that were on my starter for the changeover and I encountered no problems at all.
I surmised that the Service Manual implies this because a manual trans flywheel and press on ring gear are much more accurate in size compared to the stamped steel plate/welded ring gear flexplate found on automatics.
I must admit however that I have never heard anyone make this "shims on automatics only" distinction about fitting a starter motor to a Pontiac car.
I'm wondering if anyone else will weigh in on this.
