Three differences that I know of:

1) Different crossmember under the bellhousing.

2) The '53 has a transmission crossmember, the '54 does not.

3) The '54 has a lower kick-up over the rear axle to allow the deeper bed.

There are likely others, but these are the ones that come to mind.

It's true. I really don't do anything but browse the Internet looking for trouble...
