Good point. And make damn sure that the original part isn't still being
sold by the manufacturer. A manufacturer can change a part in one of two
ways: 1) a running production change (update) in which the part number
remains the same but the part changes, or 2) a new part number
(supersede), with the old number being shown as "discontinued" in the
parts fiche. In the first case, the only documentation necessary would
be a receipt. In the second, a copy of the relevant page in the
manufacturer's parts fiche wouldn't hurt.

If the factory shop manual isn't definitive (it never is in a case like
this), that'll be the case.

If a new part number is to replace an old one, there will be a TSB to
that effect somewhere in the manufacturer's document system. Having a
copy would be a good preemptive measure, but it isn't really necessary.
If you get protested on something like this, the TSB will turn up in the
ensuing investigation.

Yep. You could take your car in to the dealer for a repair and get it
back with something different from the way the car was originally
manufactured. Manufacturers supersede and update parts all the time.
