Already have spindles old spindles off, no big deal..put one back on last night trying to get some measurement. Can see where it might hit. don't see how caliper will hit though. Tech guru was not too good. could not explain a whole lot to me--other guy at McGaughy said no problem..Think I will try to find some good used stock ones. no guessing there. Maybe I will get 55 back on the road waiting for parts. Nothing hitting now Thanks
