Thermostat housing - same for B and B3?

[fossilcruiser]

Hi Guys-
I'm looking for the bottom half of a thermostat housing for my BJ70 (https://forum.ih8mud.com/diesel-jdm-parts/574773-thermometer-housing-1985-cdm-bj70.html). I have an offer for the part from a B engine and wanted to know if these are the same.

Any advice -or if you have the exact part- please let me know.

Many thanks!

There are several different variations, your BJ70 3B has the rad cap on the top part of the thermostat housing, the B engine has it on the radiator - so, totally different parts.
