Robert, I believe you are attempting to sort your '36, correct?
I can tell you what I have, and I will tell you I believe it is all correct. Take that for what it's worth as I have a ton to learn about this car.

Okay, I'd attached two photos of the seat brackets. You will note they are different in regard to the left vs. right seat. Lord only knows why that is. However, the Ford (illustrated) parts books backs that up. The driver side (left) uses the brackets (48-705222) with the "female". These brackets are shorter than the passenger (right) side brackets.
The right seat brackets (48-786354) have the "male" and are a bit longer than the left brackets, perhaps 3/8" or so. These are called out as "special equipment". I understand that to be for the optional seat.

The left seat is adjustable.
