COE cab sizes? shortest? narrowest?

anybody know just how wide ,long and tall any particular complete cab with hood and fenders is compared with its regular truck cab if aplicable?
im looking into building the the smallest type what ever that maybe and iof its worth the extra h***le over an easier to find parts model

anybody have dimensions or know a website? i seem to recall a good one for regular old chevy trucks but i cant find it now

 

ok so i think iv worked out for example an ad series chevy coe is aprox 2 foot shorter front to back of cab than the regular pick up this is including standard bumper location
but i dont know width at widest part (fenders)

 

I found the complete dimensions for my 40 ford coe by googling same. Bob

 

i found some bob hence my post but i couldnt find width. a 7 foot wide cab is of no use to me
so im trying to see wich is the smallest available

 

From my experience of just looking at them
The 38-47 Fords are the smallest,
but I am not sure of fender to fender lip width.
