old Campy triple inner chainring bolts needed



I have been rebuilding an old bike of mine from a fixed gear to an old
triple, and am only able to locate 3 of the chainring studs and bolts
for the granny gear. This crankset is the Campagnolo nuevo record
triple, common on Paramount P-15s from the late 70s. I am sure some
older bike shops have a few of these in a drawer, I just cannot find
them. If anyone has any I would greatly appreciate it.
