What's this part called?

I don't have a picture, but I've seen them on top of trunks.
It's just something that is bolted on top of the trunk, kinda looks like a spoiler, but not really.

it's like a rack

Hmmm, no pic...so I will guess, maybe a luggage rack?

I found a pic, it's like this

The one in the pic was on a Regal (late 80's early 90's). Never seen one for a PA, I suppose the reason behind that is, the trunk is large enough that you would not would need one. :dunno:

Yeah, I've seen on on a PA though. I saw it here at my university too! not sure where the car is though, but I've seen it, it was an earlier PA, I think 1993 or 1994 - it should fit on a 1995 though.

it would be called a spoiler. thats what the raised piece is. there are a variety of them out there. you can go to an auto parts store and they have or can order a variety of them
