If you are serious about having all original-type equipment nuts and bolts, you could spend considerable time scrounging junk yards, old barn finds, fence rows, etc, and remove the correct bolts that you need and carefully label them this time.
I have been known to be somewhat anal about bolt heads which can be seen by the casual observer. Namely the door hinge bolts which have a "TR" on the head, and clutch head bolts and screws.
