Vette Obsessed:
Better to ask alot of questions than to not ask any in my opinion.
I haven't tried to put the sill cover plates on my car so I can't comment about how they fit on a converted car.
RPO Z52 included RPO's V01, B4P, KC4, FG3, fast steering ratio, and 17x9.5-inch wheels. RPOZ52 was available with coupes or convertibles. It was also available with manual or automatic transmission.
V01 - heavy duty radiator
B4P - Radiator boost fan
KC4 - Engine oil cooler
FG3 - Delco Bilstein shock absorbers
Here are some other letters & numbers that you might find on the underside of that console door:
UU8 - Delco-Bose AM-FM Stereo system with casette
NN5 - California emission requirements
MM4 - 4-speed manual transmission
G92 - performance axle ratio (3.07:1)
D74 - Illuminated driver vanity mirror
DL8 - twin remote heated mirrors (convertible only)
C68 - Electronic Air Conditioning control
AR9 - Base seats, leather
AQ9 - Sports seats, leather
AC3 - Power driver seat
I think the paint code for black in 88 is 41.
and the grey interior codes are:
902 - leather, gray (US spelling - not mine)
same code applies to base leather & sport leather
Note for any lurkers out there: some of these codes are year specific, some are not.

Sorry buddy but I heard they only started to get things right from 22364. I understand 22363 was built on a Friday afternoon before a long weekend when they were having union problems...(j/k);laugh
My opinion on chips is to not bother with getting one unless your car is highly modified. The GM chip has a pretty good scope for "learning" and adjusting accordingly for alot of the common bolt-on mods. You may optimise what you have now by a few hp by just doing a chip but in my opinion it isn't very economical on a horsepower per dollar ratio. Personally, I would only do a chip if I knew I was done with any modifications to the car mechanically or if it was so heavily modified it needed a chip to run properly.
Most generic chips are designed for a specific combination. If you don't happen to have that exact combination on your car you may not gain anything - you may even lose power. If you have to get a chip I would have a custom prom burned locally by someone who will run your car on a dyno and tune the chip accordingly. Last time I heard you would be looking at paying between $800-$1600 to get this done. (Subject to who does the work, how long it takes and what their costs/proft margin is...)
Just my opinion.
You can tell I don't have a chip yet, can't you? ;)
If anyone feels differently, lets hear it. I know there are different opinions out there.

For all of you '81 & ups who would like to know what options your car was built with, check out

for ordering a copy of the build sheet.

Stingraynut:
If the fillings have fallen out of your teeth, you have Z51.
If the fillings have started falling out you have Z52
What I would like to know is if there is a ‘standard’ spring ie a Z53 or is Z52 standard ? In which case, on that scale, I wouldn’t mind finding a Z57.
I’ve been reading about some shock absorbers that sense a sudden jarring, around 1.5g and release fluid for 15 milliseconds or whatever to make the suspension smoother – anyone know about this ?
Those tyre sizes from Vette Obsessed – it should be 275 (x 40 x 17) not 245
