Are these hollow? I have one on my 68 that apparently isnt for it. I ordered it from Dallas Mustang and waited a while before I put it on after I ordered it and it was too late to send back. The sway bar hangs down too low. It needs to be about two inches closer up to the motor. I was thinking of heating it and bending it up. I know heating it will cause it to bee weaker, but it still has to be better than the stock one...
