Hot Rods another 1932 3w 1933 1934 seat question

I got this seat with some other parts I bought.. previous owner thought it to be a 32 3w or possibly 33 34 coupe, but not sure ??... how do you tell the difference between them... are they interchangeable?... need help from the experts.. Thanks..

 

Not a 34 5 window. The adjuster for the seat is completely different. I would say it is probably 32 3 window.
