-31 Cabriolet question.

My sweet supplier should send me door hinge pins and sent me a complete hinge set for my -31 pu. I believe that the roadster and pheaton has one kind of hinges and the coupe, tudor and the pickup has another.
A friend of me restores a -31 Cabriolet, can he use these hinges on his car? I have looked at different pics and they look as the ones for coupes and pu's but it looks like the cabriolet only uses two at each side.
Please educate me. It seems useless to ship them all the way back to U.S. if he can use them instead. But he wants to be sure they are as the originals

 

I believe the Cabrolet and Victoria share the same hinges along with the slant windshield Fordoor. You'd have to place the hinges side by side to be sure that they would swap.
