I own two older Bonnevilles, 1989 and 1990, both white SSE models. Currently doing a re-build on the 89, isn't much I haven't done, engine transplant, drive axles, struts and, of course DOOR LATCHES!, the list goes on and on. Will be painting soon!
Also parted out a wrecked 1990, have a bunch of misc parts that might be of intrest to other owners, odds and ends like the white wheel centres, interior parts, electronics, ground effects body side mouldings etc. Drop me a line if you are in need of any odd parts.
