I think the light just went on inside my head . If you have the fox chassis that is shorter than ours with a tranny that is further up, then u compare it to our body that has a longer wheel base but the tranny is further back, im thinking those distances between the tranny and rear end are the same in stock configurations. The DS spacer is needed when u put the shorter transmission on the longer wheel base.
AHHHHHHHHHHHHHHHHH. lol dont cha love it when things dont click, then u wake up and smell the hot coffee
