Lots of us would love to have that "cheat sheet", but it's hard to track down using FAM numbers. It's been discussed a number of times here on Stovebolt.comApparently the PN's for the bolts were changed over the years and don't show up in the parts manual, although the corresponding nut sizes can be tracked down which will give you the bolt diameter and thread. I believe most of the bolts you're looking at are 5/16" - 18 threads per inch, and roughly 3/4" long. I think the rod type fender supports (rear of the front fenders) might be 1/4-20 and 1/2" or 5/8" long.
