Cliff,
We installed dropped footboxes for both the driver and passenger on our EM. Big job, but it's the best improvement we have made to the car! When we bought it it had an MG pedal assembly and enough room for about a 12 year old. Now after dropping the floor 3-1/2" and building a new pedal assembly using externally mounted Wilwood cylinders, the difference is like night and day!! I totally got the idea from Dan who did something very similar on his Midstates. Thanks again Dan!
Here are a few photos of what it looks like, although they are pretty old. Ignore the gas pedal, as that's the crap the previous owner installed and we've since replace with a custom one. We also built a steel pan underneath the footboxes for extra safety. If the pics don't show up for some reason, email me and when I return home from my business trip in a few weeks I'll email them to you.
Mike
