nylock vs lock washers

["Larry Vaughan" <lvaughan@pldi.net>]

While stripping down my Spitfires, I've noticed the suspension bolts are all
nylock nuts. The rest are lock washers type. When I put it back together, is
it required to replace nylock with nylock? Would lock washers work as well?
Are the suspension bolt and nylock nuts reusable, if no obvious wear or damage
is visable?
My local auto parts and hardware stores don't keep fine thread bolts or nylock
nuts in stock. A limited assortment of fine thread bolts maybe.
