I expect the part numbers are now the same because the original parts were replaced by newer parts (in the early/mid '90s) and the old parts are no longer stocked. Just as you can no longer buy 1 or 1.2 bad radiator caps but only 1.4 bar caps that are now are supplied for all cars no matter what they came with originally.
