GM seat interchange

Here's the deal.

I have a set of seats from my 58 Oldsmobile (4 door) that I saved before I sent it off to greener pastures.

My question is, because i am looking to sell them, will they fit other GM cars of that year and possibly any surrounding years? I've searched but found nothing.

Thanks HAMBers!

 

BUMP? Surely someone must be able to lend some light.

 

No one?

 

Hollanders doesn't list seats.

Sorry.
