The main difference is in the washer functions. The 54 motor is mounted in a tilted position and has the mounting for the washer co-ordinator built into the top cover. The tilt is so the co-ordinator can clear the hydraulic pump mounting bracket.
The old method for controlling the washer by reverse turning of the wiper knob is not used on the 54 system as that washer control is done electrically. The wiper switch has a button in the center of the knob for that function. Vacuum for the washer is taken from a tee in the supply line to the motor rather than being controlled by the motor slide valve. I don't remember and cannot see in the photo if the washer vacuum nipple that is on the left side of the older motors is still present on the 54. If you do not have the nipple then you can find a 54 6v electric lid for the washer if you want to have the co-ordinator and electric operation. Those are identified by a black cap over the solenoid. 12v washer lid caps are red. The jars are the same.
If you want to use the older washer without a co-ordinator it can be done without having the nipple on the motor but you will need to connect it differently. The vacuum will now be from the motor supply side and a Trico washer vacuum pushbutton or something like it that can mount under the dash edge will be the control. You could also use an electric solenoid valve in the vacuum supply line to the washer operated by the regular button or a pushbutton under the dash.
6v solenoid valves are hard to find but Amazon does have one. Have not used it so I truly do not know if it would be suitable for vacuum control or if the ports and flow rate is large enough so it would work in this situation. If you can find something different or have 12v available then there might be more options.
