I put a Dana 60 in my '53 3600.
The Dana was from a mid 60's F*&%$. Narrowest one I could find.3.73 gears.
Spring perches, shock mounts, U-joint/driveshaft shortened.
E-brake cables restructured.
Ford and Dodge 8-lug rears have a wider center than Chev.,so the Chev. wheels don't fit. Dana from a Chev would not have that problem, but they all seemed to be too wide.
