Default Air dam replacement

Hello all, I'm looking into buying a replacement air dam. This one in particular seems great, but I'm not sure if it will fit my 1988 base corvette. It says it's for Z51 cars and fits "*1987-1989 With Performance Handling Package"(Derby City Corvette,) but it also says that it "FITS ALL 85 - 90 Corvettes"(Derby City Corvette.) I don't think my car is a Z51, but I am in desperate need of a replacement because the car currently doesn't have the central part of the dam. *It does not drive at the moment because it's being put back together after a head gasket job.* If anyone has any info as to whether or not this one will work or any other parts that are cheaper/better than the one I'm considering I'd appreciate the help. Thanks!

I had to replace mine last year because of shoddy repairs at a body shop after my car was impaled in a parking lot. I'm currently at work but I will get my receipt folder out and let you know where I bought mine from. It's a good kit, came with all the needed hardware.

Either will fit. The Z51 is about an inch lower to the ground.
