Do you want to move the rearend rearward by two inches by using the longer B body style leaf springs? If not don't use them The tech at Cal Tracks should know better to tell you that two inches longer it doesn't matter, shame on him (maybe he should ask his girlfriend about two inches longer mattering or not : grin:)
