Question about spring mounts
Nathan,
All the rivets in my frame were 3/8" diameter and I replaced them with 3/8-24 grade 8 bolts and nuts plus internal star lock washers under the nuts. I didn't realize the F-1 had fasteners as big as 9/16" diameter in the frame.
WRT the bolts vs. the rivets, grade 8 bolts and nuts have about 3 to 4 times the strength of the rivets and provide about 3 times the clamping force at recommended torque. The bolts probably have about the same fatigue strength as the rivets. It's a win situation all around with the bolts.

Question about spring mounts
I'm gonna enlarge the holes to fit 9/16 bolts. Since 1/2 is to small and 9/16 is slightly to big. With sizes I go by the head size since it gets confusing and when the hardware store has a wall covered with different bolts I will just find one with the right head size and length.
