Nope...not all later models were in the rear spoiler...they went back to the
high mounted inside the hatch light.

   You would be surprised at the  things Idiots do to cars.  They will try
to  counterfeit GTA's, IROC's, and 92 RS cars. Hell if  I like the way  one
looks, even  if it started life as  a base   model  Ill buy it.  If it
happens to have GTA emblems  or IROC  decals(or painted lettering) on the
doors, Ill remove it. Then sell it for what it  is after  I'm tired of it.
Ill get pretty much what it would as if it were  a GTA or   IROC, because I
will make  it clean,  and   look good.

   A buddy of mine has a 1987 Monty Carlo LS. I sold  him my 1988 Monty
Carlo SS parts car (for next to nothing). The LS was  hit across the nose,
and it's getting the frame from  under a 87 Cutlass Classic. Someone asked
me once Will the SS parts  make it a real  SS? I  told them "Not really, nor
will it ever be claimed  to be a SS".   Just a cool  looking  car saved from
death.
