bolster structure?

[E30 Wagen]

Hey, i've got a chance to buy a pair of heated cabrio seats (sport) for $10. However, the driver's side bolsters are gone - the foam is basically worn completely off on the bottom and on the back rest.

I have a set of sport seats but the left bolster is way bent out. I'm wondering if it's possible to take the bolsters of my seats and put them on the cabrios. I don't know if the bolster structurs are part of the frame and are welded on.

i seached and didn't find what an answer and i didn't feel like jacking somebody elses thread.

all the foam can be removed from any sport seat frame

they are constructed using bent steel rods to give the skeleton, then covered with a foam peice then by vinyl/leather.
