If the RPO sticker is no longer there then you can get a reprint of your window sticker and the build sheet from the National Corvette Museum.
They just need your VIN# and some cash.

Per Mike Antonick's Cor-vette Specs C4 book there were 5,726 1988 Corvette convertibles manufactured with the Z52 Sport Handling Package.
RPO Z52 included RPOs V01 (Heavy Duty Radiator), B4P (Radiator Boost Fan), KC4 (Engine Oil Cooler), FG3 (Delco-Bilstein Shock Absorbers), fast steering ratio, and 17X9.5 inch wheels. Available with coupes or convertibles. Available with manual or automatic transmission.
Cost was $970.00.
On a side note, the most popular convertible color was Bright Red (1,906) and the least popular color was Silver Metallic (131).
The most popular option on the 88 verts was Power Driver Seat (7,288) and the least popular was Performance Axle Ratio of 3:07:1 (166).
If you happen to own a Silver Metallic convertible without a power driver seat and a G92 Performance Axle Ratio then you have a rare one!

Mine is red convertible, I have two fans, and I have the Bilsteins. How do I identify the Engine Oil Cooler?
Thanks again CorvetteRon!!!!

My memory is a bit rusty here but if you get it up on a lift you should see lines coming from where the oil filter attaches that run to a small finned cooler up front by the radiator.
Others that are more knowledgeable can step in and correct me if I am wrong.
Here is a pic of the aftermarket kit that Corvette Central sells for $315. It should look something like this:

That is my baby but how can you tell from that pic?
For the record, I can confirm it does have Bilsteins, it has the 17"x9.5" wheels, has a main and an aux fan, but I cannot find the oil cooler (as suggested above). Anyone tell me where that would be? I have looked in my Chiltons and in the engine myself and can't really identify where it is.

Look at your oil filter, the cooler has a boss (spacer) between the block and filter with two ruber coolant lines coming off it, follow the hoses.

I found the build sheet in my center console lid! I've been able to figure them all out except for "MH5". Any ideas?
