is the cab off a f-600 the same as a f-100 cab i was told the fenders we just bigger but i cant tell by looking at it?

 

Yes....all the cabs for 1956 F100 and ---f600 are the same. Except for the coe(cab over engine) type and the cab and doors are a little different.
The fenders are larger(opening) but all are the basically same as far as mounting.
I just delivered a set of 56 fenders yesterday.....the bigger fendes are not repopped as of yet....so keep the stock ones till you find others....BILL

 

Yep, what he said.

Do the fenders just have the larger opening or are they wider too? I haven't put them side by side but when I was looking at a '53 F100 earlier the fenders seemed to be not nearly as wide as my 600 Fenders. Anyone know for certain? Or better yet got pictures side by side?
