Default Shimming the starter?

On page 6D2-3 for the starter noise diagnostic. It said to shim 0.015" to outer bolt only . How the H*&^ do I shim just one bolt? Do I cut the shim or just put the bolt thru one hole and leave the other out (no cutting). I have the shim just like the picture show in the book.

Remove the short 9/16" bolt and loosen the long 9/16" bolt. Slide the shim in, the open end of the shim will slide between the long bolt and then line up the shim for the short bolt. I never heard of shimming one side.

I did like you described then I broke the ex manifold flange. Had to reweld it. Looking thru the 1988 service manual on the starter problem and it read noise while cranking shim outer bolt only and if noise after engine started shim both. I cut the 1/64" shim in half and shimmed the short bolt. Thought that there was no space for me get my hand in there but there was so it can be done.

There are long shims that go under both bolts and short shims that only fit under one bolt.
