[Gmecm] RE: '727 mounting

[Robin Handley]

Hello Clair,

In the original position that I mounted it, the ECM sat on 'stilts' which 
are about 20cm high. This lifts it high off the sill into the wing, and it 
sits behind the inner wheel arch - so it is well protected from wheel 
splash. I have had no problems in the few years that it's been there - but 
I've never driven it through deep standing water. The car is very low to the 
ground, and there is no room on the firewall, unfortunately.

As part of my current sill work, I was planning on fitting a water shield to 
the leading edge of the sill (covering the gap that the inner wheel arch 
leaves).

As a rule, this is my dry weather car, but obviously it needs to be prepared 
for unexpected bad weather.

Thanks for your help,

Robin
