The Sparco seats that are usually used racing are Rev and they are 455mm wide. They just fit with a bit of minor trimming to the rolled edge just at the front.
None of the OMP, Sparco, Cobra or Recaro reclining seats are this narrow width with the narrowest being 500mm.
On the fixed back seats however, I’ve had good results with the side mounts which allow considerable recline (short legs, long arms). And have the benefit of feeling like you are sat “in the car” not “on the car”. Not an ideal answer but unfortunately the realities of the Morgan cabin/chassis design.
