really depends what you want from the car, a set of tramp bars on rear leafs with a twin cam anti roll bar a lot of people love.
bear in mind if you link the rear you then have the watts or panhard rod to fit as well as butchering your rear seat bases to fit over the link boxes.

What I would advise for a fast road car with a little track is convert your existing front Bilstein legs to coilover by the adaptor kit from motorsport tools.
I would then spend the money on a twin cam roll bar and upgrade the diff to a 3j plated(noisy in use) with atlas style 18t sideguard and 2 piece shafts.
I would highly recommend Rally and competition equipment for the axle parts as they are escort specialists and build axles themselves.

hope this helps
