You absolutely sure about that body molding color year, Mike? Because the factory literature I do have lists 91 as the first year for the LX Coupe getting body colored side molding.
The Pony wheels in the 1/24th scale mustangs scale out to 15" versus the 16" they should be. So, by putting them under a 1/25th scale car, they will more closely represent the 16" wheel they are supposed to be.
On the Mass Air Meter, if you were doing a California car, you would be able to do a 1988 as well with the optional parts Mike listed. (As California got MAF in 1988 while the rest of the nation had to wait until 89)
In the GTs, 1990 didn't have the armrest pad in the center console (I believe the LXs were the same way). The armrest returned in 1991-93.
Pony wheels (the 16" wheel) became standard on all LX 5.0s from 1991-on. The ten-holes became an SSP equipment list item, same as the Lies-Neveille (spelling is more than likely incorrect) 130amp alternator and the Silicone coolant hose kit. Later examples had beefed-up floorpans and revised Lower Control Arms (from the 4cyl fleet/taxi use bin in place of the 5.0L units).
As I have already stated, if you want a good breakdown of SSP by year, check out www.sspmustang.org. Places like Corral.net, foxbodyforum.com, foureyedpride.com, ultimatefoxbody.com, and several others are good places to look for your civilian LX 5.0L Coupe info.
