Are you sure you arent thinking 41 and later merc? which wasnt wider, but streched a few inches behind the wheels, 40 merc is basicly a rebadged ford with a different grille and on coupes a different roof line
IS a 40 Merc clip wider than a 40 Ford? The extra length in the 39-40 Mercs is in the body shell. The later Mercs use the Ford Body shell and a longer nose.
I'm sorry, your mistaken, the 40 Merc in all forms is definately a different platform than the Ford....
I would look for a different cab,an earlier one. i think it would flow better. NICE! a little to much street rodder for me,but nice any how!
IMO You would need the earlier rear fenders also to make it look right. Plus if that’s the front end your planning to use (pictured) ? That would be a shame….killing that sedan to build a truck……….dumb
