I am getting a 1989 Olds 88. What other GM cars are kin to the Olds 88 that I can get parts from?
 
Sharing the H-body with your 88 are the Pontiac Bonneville and the Buick Lesabre. On the very similar and closely related C-body, and sharing the same exact powertrain are the Olds 98 and Buick Park avenue. Perhaps also a cadillac... but I'm not sure on that.

Your best bet for parts is any one of the above which are of the same body style as your car. The H and C-bodies were significantly updated in '91 and '92 (depending on the model), but will still have some common parts to your car. It just depends on what you need.
 
The Cadillac Deville and Fleetwood up until 1993 were on the C Body platform similar to Oldsmobile Ninety Eight. The Fleetwood switch the the rear drive B Body, but was known inside GM as the D Body. The Aurora was on the same platform the G Car platform wirh Buick Riviera 1995-1999. It then was on the G Car platform with Buick, Cadillac and Pontiac from 2000 forward. As stated above, the H and C Bodies shared similar parts with other GM cars from other divisions.
 
There were two Fleetwoods at Cadillac for a while. When GM downsized and switched the RWD C Bodies to FWD C Bodies in spring 1984, Cadillac had Fleetwood and the Fleetwood Brougham. Fleetwood Brougham became Cadillac Brougham in 1987. The FWD Fleetwood was still a C Body, but sharing looks and parts with Deville with more features and options. This was until the Fleetwoood name was put on the B Body (D Body)Cadillac in 1993. That FWD Fleetwood became Sixty Special in 1993. Then in 1994 you had the FWD Deville that was placed on the FWD K Body platform shared with Eldrorado and Seville. Then the C Body was dropped after 1996. The B Body platform(Roadmaster,Caprice,Fleetwood) was dropped after 1996 in favor of suv's and trucks. The 1996 model year was the last year for the C Body because the Ninety Eight was dropped and replaced with the H Body "Regency" and Park Avenue went over to the G Car platform in 1997. Regency ran for two years(97-98) and then the Ninety Eight trim was used on the 50th Anniversary Edition of the Eighty Eight. The Seville switched over to the G Car in 1998. Eldorado died a few years after that. Then 1999 was the last year or the H body Eighty Eight, LeSabre and Bonneville. The Bonneville and LeSabre went over the G body platform. Eighty Eight was dropped the same year the Cutlass name was after the 1999 model year.

The G Body was used all on GM luxury and fullsized offerings. The Aurora was dropped after 2003 model year.The Seville switched to RWD on the sigma platform. The Deville is on the updated G platform with the Buick Lucerne for 2006. Park Avenue and LeSabre and Bonneville were all dropped as of fall 2005.

Rumor has it GM is working on a Zeta rear drive platform program they dropped and brought back. It is supposed to spawn Chevrloets, Pontiacs, and Buicks.

*** A side note, Oldsmobile before its demise was pushing GM for a sigma based Aurora.

Thanks for the info, and plenty of it! Not yet having the 1989 Olds 88 in my driveway (Due Oct. 23) my knowledge is limited as to what I graft from other similar framed cars. I do know that I will be looking in junk car lots for a front strut brace from later Olds 88 models. We'll have to see else we need and what we learn from the forum's recommendations, such as high flow airfilters, air intakes, cat backs, suspension, mufflers, etc. We will listen to any advice or suggestions.
