Hi Chris, while my car used that same coil mounting location (red hole), there doesn't seem to be much consistency between cars. I attached photos of my original insulation to show the indentations left by the coil bracket. The 'blue' location in you photo seems more logical, which - - IF my bracket is correct - - would put the coil right next to the voltage reg, and as you suggest probably require mounting the coil updside-down.
Picking through several dozen marginal photos I did find a few cars showing that upsidedown configuration. That said, there seemed to be at least as many examples with the coil upright, but located further to the rear of the car, ~3-5 inches behind the voltage reg. (Unfortunately none of the photos clearly show the mounting holes used, or details of the bracket). There were a few other examples using the 'red' hole, but with the coil mounted diagonally, at various angles. And finally, 8MA566 and 8MA632 check in with the coils on the LH side (!!), in what appears to be a consistent location. I ASSUME they were both modified, maybe by the same shop?!
Does anyone recognize the bracket illustrated in image #3, or have more definitive coil info?
Water valves are easier....should be one on each side, in identical riveted brackets. No cables were fitted...opening/closing valves was a manual operation. Must have been one of those corners cut as the car was rushing to production
