1937 Ford Differential Gearing
 

My 1936 coupe is set on a 1937 chassis with 1937 transmission and differential. When I purchased the rolling chassis I was told that it might have been under a pick up truck. The gearing seems rather low. Would a truck differential have had a lower gear ratio than a car? On re-build the trans seemed "normal". Thanks for any insight.

Not necessarily, especially if the CAR was destined for a dealer in hilly or mountainous country. Any ratio was possible in either car OR pick-up.

You can almost positively tell whether your chassis was under a car or a truck by the presence of, or by the lack of the two box-like items riveted onto each side rail noticed just in front of the rear tire in the picture BELOW. PASSENGER CARS had those boxes riveted to the frame rails on '35-'40 CARS.

'35-'40 PICK-UP TRUCKS did NOT have those two appendages on their frame rails, as in the picture BELOW! DD

stock 36 would be 4;11 ,from the service bulletins 37 --3:78 unless it was 60 hp then 4;44, as a option a 60 could have a 4:55 and the 85 could have 4:11 or 3:54
if it is a 37 it would have cable mechanical brakes

Thank you. That is very helpful. Yes, my frame has the boxes.

Thank you for the gear ratio info.

So, it was originally under a PASSENGER car body. DD
