Wasn't there some kind of law requiring the manufacturers to keep all parts available for a specific period of time...........10 years maybe?

I suppose a '90 Taurus is out of that window.

With regard to getting M/B parts, I've already encountered problems with buying broken pieces. I need a clip or a fastener. Nope. Not available. Must buy the entire assembly at something like $500.00

M/B may be somewhat better at keeping older parts available, but, they are not the holy grail.
