MG MGB Technical - Electrical Switches UK vs. US

I have a RHD UK-spec 1973 MGB. Can anyone please tell me if the directional signal/high beam/headlamp flasher switch, the wiper/OD/horn switch, the ignition switch and the instrument voltage stabilizer are interchangeable with US-spec parts?

Also, the fuel guage is very erratic. Shows a bit more than it really displaces in the tank. Is this a symptom of a bad sender, a bad voltage stabilizer or a gauge that needs calibrating?

Hi Tom,

The UK part numbers are:

Directional signal/high beam/headlight flasher switch 37H8101 fits GHN/D5 360301 to GHN/D 41000

Wiper/OD/horn switch (seems confused in reference books) might be BHA5251

Ignition switch 37H7708 original chrome bumper - replacement switch 37H54934

Voltage stabilizer BHA4602 all years

Your local MG parts supplier (or Moss USA) might be able to recognise these numbers.

Hope this helps

Much, much obliged, Peter. Thank you.
