Technical 55/6 Ford window Reg's

I've got a Ranch Wagon which needs a set of window regulators for the front doors,
Can anyone tell me what the differences are between 2 door & 4 door reg's?
We didn't get any factory delivered 2 doors here in Aus but there are stacks of 4 doors about.
It doesn't have factory winders so can't compare the 2
Thanks in advance

 

On the '59 Ford they are the same. I cannot see them being different since they both function the same way.

 

Are the channels that hold the Glass the same length?

 

All I know is the '59 in great detail. I have used door guts from a donor Ranchero and Edsel. I still have the Edsel door which is in great shape.

 

@bobss396 thanks, I'll try to track down a 4 door one & see how we go...
