3.125...(at least, that's what my old 60 had...and Matt and I had the same u-bolts on the rear)

Either way..they don't make a 3.125 u-bolt so buy some 3.25" ones....:smokin:

I just thought of this: I think the early style non triangulated housings are 3 inch. the later style are what I refer to at 3.25"
