Pat,
The fender bolts and nuts are 1/4 " 28 Threads per inch. Most of the bolts and
nuts etc use fine thread 28, 24 threads / inch etc. My suggestion to you is to
buy a set of taps and dies for english (not metric) nuts and bolts. You should
get a thread gauge just to be sure. Sears has a good set. There are some off
sizes such as the carburator but most of the body and engine hardware use std
english fine and coarse thread sizes and english diameters.
