All I know is that Revington (UK) recently announced a coil-over
conversion, and that some welding is required.

I'm very interested in hearing about this (ie does it work, how
much, ride height/spring rates and will 15"x7" rims fit?).  My 
initial reaction is that it should be great!

Any folk with some experience out there?
