I found a narrowed rack and pinion for a G Body (I think you make your own call) at http://www.quartermax.com Part# 203108-1 for &199.00 I called flaming river they said from pivot to pivot it was 19.29" I checked my car and from A Frame pivot to pivot it was 19.25....looks good to me. I got eveything I needed to change out my steering for under $400 bucks....It will be this summer before I will get mine done so if anyone does it before me please post........Good Luck
