I think Mark may have been the first.
I have been trying to help out with finding some parts and was forced to do a little research.
From what I can tell the hub caps are GM part number 15661128 used on the PH1 steel Chevrolet wheels from '95-'05
The lug caps are what holds the hub caps on and are not the same caps that are used as covers on the alloy wheels. These caps have a shoulder to retain the hub cap. Our stock lug nut covers do not have this.Gmparstdirect wrote:GM PART # 15661128

The caps needed are GM part number 15661036
They are bagged in packs of five, but that may be the price each? Or it may indeed be for a package of five? A bargain if that is the case.GMpartsdirect wrote:GM PART # 15661036

Both items may be a little hard to find. Around here hubcaps are not prized and saved as such. That and the majority of vehicles seem to have alloy or aftermarket wheels.
There are other options going back to the early 90's for lug nut caps. They differ a little though. Cutlass, Aztec, Grand Am and assorted others use similar covers to retain the hub caps.
