Re: a few missing unkown rpo codes

I ran some through http://www.camarosource.ca/php/camar...year=1986&tm=1 and got results for these . . .

B9G - ORNAMENTATION B/S MLDG REAPPLY TO RR DOORS ONLY
C4B - PERFORMANCE PACKAGE ENGINE UPGRADE
E7Z - SENSOR VEH SPD - DELETE
GC5 - FLEET INCENTIVE KEMET ELECTRONICS CORP. (C/G/H/K/U/W-TRK CKGST)
GC6 - FLEET INCENTIVE EDWARDS LIFE SCIENCES LLC (C/D/U/V-TRK CKST)
YE2 - CONVENIENCE PKG DECOR LEVEL #2, LOW TRIM
YT9 - FLEET PROGRAM EXPOSURE INITIATIVE I: C/F/G/H/J/K/M/N/S/U/V/W/Z- TRK CKGMPST
Some come back kind of wacky if you don't mind me saying. No idea what they mean. Some have the same results here too . . . http://www.c2e.info/rpocodes/
