I have aquired an escort axle casing and halfshafts from another axle (I left the diff because it was siezed solid

Its already been modified to have anti tramp bars (the sort with 2 bars on each side). In order to fit it im planning on doing quite a lot of fabrication. I think im going to have to mount the anti tramp bars through the box section under the rear seats, and im anticipating having the front mounts just inside the passenger section so I can actually take the things off without having to cut the box section up (again). I am planning to put "channels" inside the big box section for the tramp bars to run in.
Next I am planning too fit coil overs on the rear, to do this I think I will have to put turrets in the rear floor these will be obviously welded in to the floor pan with spreader plates etc and box sections above and below the floor connecting the 2 turrets. I am going to keep at least the top leaf for axle location, and will decide how many of the others I want to keep when its all uptogether
(I am also anticipating junking the front suspension and sorting something a bit more modern shortly)
What do people think?? Have I missed anything obvious? BTW this is a fast road car, at the moment its got a 90hp engine but im not anticipating that that will stay in forever and I would rather get the suspension and brakes up to scratch before putting something more powerful in!
