Gary, Gary from Cleveland, Ohio again. The only solution 25 years ago was to install the lower leaf spring/lower shock bracket from a '68-'70 AMX or Javelin because it used a through-bolt style for the lower end of the shock. I had done what you have and installed rear air shocks for a Hornet station wagon thinking that they would be a little longer than the standard shocks. I was wrong, all that happened was the ride was terrible and I broke three right side lower brackets ( the piece that the two U-bolts bolt through). After much research I discovered that the early AMX shocks were about 2 inches longer and by using them in conjunction with a set of Lakewood traction bars (for the AMX of course), it was no longer necessary to pump the air up to the max to get clearance for the L60's I had installed. With this combination I did not need extra long shackles either. I am still using the same traction bars and rear air shocks today that I installed 25 years ago with none of the problems I had in the very beginning. Gary 'The Mix' , from snowy Cleveland, Ohio
