Ahhh yes, parts.
The sandwich plate is a 1/8" BSPT thread. Most US spec sensors are 1/8" NPT. You will need an adapter. Autometer makes them. I picked up mine from Autozone online. Part# 2269. $12.99

The MWR pan sensor mount is threaded (I believe) 1/2" NPT.
Picked up a 1/2" NPT/1.8" NPT adapter at NAPA.
Got the SPA Design gauge at Bimmerworld.com:

You want the Universal Type C. You will need a large (24mm, I think) metric socket to fit this part. Good time to buy those big sockets you don't have.
Use thread sealant on all of the ports, adapters and sensors. Careful on torque as you are dealing with brass. Time to buy that 50-300 in. lb. torque wrench you always wanted.
Have fun!
