No offense, but the guy doesn't know what he's talking about. You can't generalize Campy/Shimano as incompatible, because they have both used several different tapers over the years.
More specifically,
after 1985, Dura-Ace used the same taper as Campagnolo. That probably didn't change until Campy started using ISO taper (1991 or 2). Dura-Ace didn't start using JIS until they went to cartridge BB units IIRC.
ISO and JIS didn't exist prior to about 1991 so anything before then is what it is. Even after that point, the standards are voluntary.

The C-Record spindle will fit in the crank, sure. But it is not the right length. C-Record are either 109 or 111mm (depending on frame clearance,) Super Record will be either 113 (before 1978) or 115.5mm (1978-on). Your '80s setup would use 115.5mm then.
C-Record and Super Record used the same cups, FWIW. Alloy cups with steel races, 3/16" balls. They do not use the same spindles as the standard 1/4" ball BBs.
