Personally I would save your money and not go coil over, as you dont gain anything.
Join a local club, I happen to be an active member in a Jeep club (no I don't own a jeep) Even if I didn't have the necessary fabrication skills there are quite a fewin my club that do, and they would be more than willing to help me out. This once again proves the old addage.....It isn't what you know, but who you know!! (and how much beer you can buy to pay them!!)
I am going to be running a full custom suspension. If I had the $$$ I would have bought the suspension pieces from a Range Rover(my daily driver) or Defender, but since I could get the Jeep TJ linkages cheap, I decided to go with them instead. I will just re-build them as necessary. The finished suspension willl be more like the Range Rover than anything else.
