[Roadsters] Spring Bolts and Specs?

[Daryl Smith]

Does anyone have the bolt diameter for the bolt which goes through the eyes of the leaf springs? Front bolt and rear shackle? I would rather not take mine apart to check it if I don't have to. 

Can anyone also confirm the stock spring rates @ ~700 lb/in front and ~150 lb/in back? (found by searching forums @ 311s.org)

This site lists the front at 522.5 lb/in, but doesn't seem to list a rating for the rear....
