Ladder bars/stock frame/rear coilover length?

we had to move the upper support back to line up moser. Chassis Engr makes a different bracket that fits a rear with a brace on it....

dana 60 cause sooner or later the ring and pinion on a 8 3/4 will eat the teeth,,,,,just had two 8 3/4 pumpkins repaired with new ring and pinions from the other cars...they got a dana also...
that duster is scheduled to have the 360 removed and a 408 installed...plus it leaved on a transbrake....
now if the dana 60 only looked like Dana Delany......i would be hugging that rear forever....lol
