Does any one here knows where I can get the original or reproduction seat cover for my 1983 Olds/Hurst and the center console which is grey (color)?

 

GBodyParts.com has new seat covers.

I believe their stock of Sand Gray is less (in quantity) than the Maple Red.

While I believe the Chevy consoles are available ... I don't think they have them for the Olds.

Probably gonna have to put out some feelers and/or keep an eye out for a used one.
(& you'll probably end up having to paint to match)

Can't recall if there is a difference with the inner plastics with the Lightning Rods .....

And/or if the consoles can easily be broken down/inner parts swapped around vs having to modify/cut anything up in a standard console etc etc.

I wanna say yes they can ... but I wouldn't swear to it.
