I am going to be replacing my suspension and frame member bolts and I am not too sure where I will be able to come up with the exact replacement bolts I need. Does anyone have a good source for replacement hardware? Can I substitute a Grade-8 coarse thread bolt/nut of the same dimensions for an original fine threaded bolt/nut (1954)?
