M52 to M20 instrument cluster coolant temp sensor adapter

Well, it appears some m20’s have the smaller threaded sensors – m12x1.5, and the m52 head has the m14x1.5 thread, that’s why if you swap a m52 you’ll need to find a suitable sensor or make the m52 one work with the e28 dash … or get an adapter.

Please note that adapters now are made out of aluminum.
