Not a part or for b-bodies, but anyway....
Have an almost new Haynes manual #38031 which covers the following:
Cadillac Eldorado & Seville 86-91
--------- Deville FWD 86-93
--------- Fleetwood FWD 86-92
Oldsmobile Toronado 86-92
Buick Riviera 86-93
It goes for $25 in the parts stores. I'll take $10 for it at any of the events. $15 shipped through the post office.
The car we got it for is long gone and we have no intention of getting another of those listed.
