I bought shocks for 69 flh from J&P .. Im a cheap bastard. They will not fit on existing studs . They are 1/2 inch inside the metal bushing. The studs on my bike seem to be 5/8. If i remove the bushings they will fit but I would think they need to stay . Anyone run into this, maybe know where to get the right size studs ? Are all shocks now a standard 1/2 inch holes?
