Mike,
You have the wrong Jag rear. I had to narrow my control arms and have new half shafts made when I went to Trigos on my Contemporary. You already got the tires and wheels, what's a few more bucks?
CWI can supply the control arms on an exchange basis and the local driveshaft shop can make new halfshafts.
The Trigos do look much better than the bolt ons.
