Please verify part#

Hi,

Came across a DME, but not sure if its applicable to my car.
Part# 911.618.123.20 can someone let me know for what year this DME is for?

I was told it was used on 1988 911, and should work for a 1984 as well. But I can't find any reference to that part number

thanks

My catalog shows an 84-86 DME to be 911 618 111 05 and the 87-89 DME to be 911 618 111 20 or 911 618 111 16
