I am slowwwly doing this also, but have tubbed the rear for more suspension travel and raised/strengthened my upper shock mounts so they will accept coil overs, I will be using eyebrow flares so can use wider tires also, my outer fender is severely cut away giving me loads of tire clearance.

I am building my own 4 links using rod ends, equal length control arms and a panhard, my floor is being modded to fit the longer upper arms in

Car is aimed at being a road racer primarily.
