Quote: just completely forget about the driveshaft measurement!
you see why im asking? some swear by the shaft----some dont use the shaft in the equation !
yea I used to think that way also! however dr diff the guy who messes with rears for a living says to go off the tranny and rear so I use that all the time now and forget the rest... less headache that way and it works! for the record I am at -4 right now...
