Adding tilting mechanism from comfort seat to a sport seat out of a sedan

[Stanfendt]

Basically my question is if it's possible to add the tilting mechanism from the comfort coupe seat to my sport seat that came out of a sedan?

From e30zone.net wiki:

Front Seats


While front seats are a standard feature in most cars, a few variants were available for the E30.

The key difference regards tilting; seats fitted to a 4-door or Touring do not have a tilting handle like those inside 2-doors and Cabriolets. However, the seat base of all cars is the same, and all seats can be dismantled and rebuilt to tilt if required.
