well I'll start here...
I have been a Pontiac fan since the '50s, when my Grandfather had one. My Dad bought Pontiac Bonnevilles, and Catalinas all through the sixties and into the nineties.
I myself have owned eight Pontiacs, including a new 1969 (ordered) GTO in 1968, a 1967 H.O. Tempest OHC six I bought used in the mid-seventies and rebuilt the engine, a '73 Gran LeMans I picked up for my wife in the early eighties, another "Bonneville" (1986) I found for my oldest son, and the vehicle I am now trying to sell parts off of.
Generally just the "wheels" since they are sort of unique for the time, and the vehicle they are on is literally "worthless". These are 13", five bolt "turbo" wheels made of aluminium, and an option for the Fiero at the time.
I have looked around, and even though they are listed mostly they are NOT AVAILABLE AT THIS TIME on most sites selling wheels. Mine have both the lug caps, and the wheel caps although the Pontiac logo has long disappeared from the wheel caps on a couple of them.
If anybody is interested in those wheels, let me know. I would hate to just let them disappear into a junk yard.
