I'm looking at putting highway pegs on my engine guard and I want to be able to make the maximum amount of adjustment. The P&A Catalog had two kinds that both mention 360 degree adjustability. Part numbers are 50832-07A and 50828-07A. Can any one explain in simple terms what the difference between these two items is? Anyone have these exact items mounted on their bikes that could give me some feedback? I'm on vacation or I'd scoot to the dealership and look at both of them. Thanks.
