TAMD73-P Fitting size

[tico]

Anyone know the size of the square on the end of the plug that retains the anodes in the Aftercooler and heat exchanger?
Feels like 1/2" but not sure and 200 miles away.
Source for a female socket to fit.... it's very tight!
TIA

Sorted (i think)!..... modified 1/2" drive extension.

yep, I use two 1/2" drive sockets welded together. Fits perfectly.

yep 1/2 inch but the ones up by the pulls you need a spanner in as can't get sockets in the space
