Since you've had 100 lookers w/o an answer, I'll throw in a "Maybe". While looking for a
'36 seat w/ the hinged "flip up" seat back feature, for storage, I was told any coupe seat
from '35-40 would fit.
To be certain, you need to measure the front and back width of your seat bottom, as they
are tapered toward the front. Have your prospective buyer do the same, but across the
floor pan at the 'B' pillar, and a second measurement about 26" forward of the 'B' pillar.
Ideally, there should be about 2" clearance on each side, from the seat to the door or
pillar.
(For the time being, I've settled for a nice '35 seat w/o the flip-up feature. The '41-48
sedan seat I had mocked up was a tad wide, just barely fitting inside the doors.)
