1992 Option Code 75U

[Jeff B.]

Just bought a 1992 Corvette and have decoded all the RPO codes, except for code 75U.
Cannot find that option code. Anyone know what that one is?

Jeff - first, CONGRATS on new purchase! second, is car DARK RED METALLIC convertible by chance? reason I ask 75 is the RPO for that exterior color, and believe the U could be option for interior color and/or soft top or both. third, if not this color then might be possible the RPO was transposed and should be U75 which is power antenna. Just throwing thoughts your way.

Thanks Dave! There you have it then DARK RED METALLIC is the primary color

Thanks to all for feedback. The car is dark red metallic, and is a coupe. The RPO list does show U75 (power antenna), and the 75U which is the body color. The interior codes are 64I, 643 and 649 (beige interior).
However, it shows QA1 wheels (17x9.5), but it DOES have the 17x11s on the rear with a funky looking offset of the read end. The wheels appear to be factory Corvette wheels, but fronts are definitely narrower than the rears. Don't quite understand this discrepancy.

All 1992 Corvettes except ZR1 were equipped with "painted" "saw blade" 17 X 9-1/2 wheels at all four corners. Any other wheels, original type or not, were added. The 11" wide ZR1 wheels do not work well on a non ZR1 because the ZR1 rear body was wider to accommodate these wheels. Without the wider body, the 11" wheels and associated tires don't look right.

agree with Joe on wheels - NOT original to the car

"U" indicates the primary body color. "L" is the secondary color, and many GM plants utilize both "L" and "U" codes on single-color vehicles. Interior color (trim) is "I". The seat color and material are a separate code. There is a code for the top color, but I don't recall what it is offhand.

Yes...And If I remember correctly the U is the primary or upper and L is the secondary or lower color, a hold out from the two tone paint days
