TONS of variables here...LHD or RHD...what year...what market (USDM, JDM, EDM)?
Looks like the only 2 versions left in the US Parts Catalogs are:
91-01: 83570-SL0-A02ZA
02+: 83570-SL0-A03ZC
But for 91-01 this will not be the original color for certain years. IIRC there were 3 different finishes offered from '91-'01 (might have only been 2). But the catalog now lists the same part number for all years and mentions that A02ZB has been replaced by A02ZA.
Might want to reach out to Marc [MENTION=33290]SpeedyPartsJapan[/MENTION] and check out mitamotorsports.com to see if he can get all finishes still.
