When did the midyear body shims for from slotted to square? Do all '63's use slotted shims. The '63 shop manual has a great photo of the slotted shims and bolts. Lots of clear illustrations in the shop manual. The frame page with dimensions is a good reference. Being rather new to the DB I don't see much reference to looking in the shop manual. Nice clear pic of the front shock washers that I was asking about. The original manuals have much better pics that the darkened repros.
