Mastech MY64 Multi function socket

[StevenNi]

Hi guys, it would be great if someone could help.
Looking for something in the basement I found my good old Mastech MY64 multimeter, I would like to use it again but I lost its MS3204 Multi function socket somewhere so I can't measure capacitors and temperature.
Does anyone know or have a diagram of how that Multi function socket is made, I would make one just right to have some fun.   

Here is a picture of what the multimeter looks like, and the MS3204 Multi function can also be seen in the picture.
