Need Help & Info from you 80's Winston Cup Nascar Guys

[Stg1Regal]

Been Searching and surfing the net high and low for info on the 80's Buick that were in NASCAR/Winston Cup.

I can find who drove them,what place they finished and when, and some pics.

But wanted to know if anyone knew of the specs or have close up pictures of the "flared" Fenders and Quarters?

And also the Specs or close ups of the rear wing?
How it was attached , and moved up or down for down force?

Thinking of doing my Regal in a tribute format to the 80's Winston Cup Buick Regal cars, but with my twist on a modern version.

Thanks
