I went through this wil Moss as well but did get a correct spring for my 73
GT the second time. The length of each of the 7 leafs were much shorter on
the second set, thereby letting the car settle down to a ride hieght of
13.5" to match the front. The first set of 7 leafs Moss sent put my ass end
up at 15.2"
I added a lowering block to the first set which brought it back down to a
resaonable 14.0" but the ride was just too.... juoncey (yes jouncey not
bouncy, meaning short sharp rebounds but controlled.)
when I put on the second set (shorter length leaves).. The ride is PERFECT!
the car is perfectly level at 13.5" +/- 1/4"
and OB rides beautifully
