The above noted control board comes in a plastic case that will not fit in the location where the old board came from. Appliance parts pros confirmed it to be the new retrofit part for my refer, #msd2757aew. What to do?

[JWWebster]

It ain't gonna be a perfect fit but remember this: the new part is protected from corrosion better.

[tgoods]

It will snap into place.  Don't worry about the screws.

[RegUS_PatOff]

the "older" style was "hokey" (did I say that ?)

This is the OLD (notice the 18-pin chip) 61005988 ADC failure-prone Board
NO LED

It has the L1 - TEST (lower pins on connector)

The "newer" ADC is a better design..
Newer OEM 61005988 (8-pin chip) 61005988 ADC Board...  L1 (but NO Test pin)
NO LED
Manual Defrost Cycle is tested by cycling the Freezer Cold Control 3x within 6 seconds and leaving it on MAX


 
There's also a 3rd party replacement ADC with a diagnostic LED ..

The ADC with the LED is the non-OEM ER61005988 (16-pin chip)  or PCB870A0180C
but I like it better because of the Diagnostic LED.

The control employs non-volatile memory technology to store system fault conditions through power outages.
Faults detected include, thermostat, compressor, and defrost heater failures.
Fault codes are displayed by the circuit board LED (light emitting diode) that flashes a specific pattern for each problem type.

It comes with instructions.
