Hi Lakshan,
I'm using 300tdi axles and running gear. Unfortunately the ENV's are staying on the original leaf-sprung chassis. The gear ratios would never match up to the 300tdi tranfer gears.
Unlike normal series axles you can easily change the ratios using Range Rover diffs, but ENV's are in a world of there own...
When its finished it will basically be a 110 300tdi Auto with a 2B body.
did you use normal 110 axles and Salisbury rear axle?
Regards Mike.
