Our favorite part of the kit is probably the pulley, which was designed to resemble the water pump pulleys. When left in its natural aluminum finish, it dresses up the engine compartment; painted, it blends in and looks like it could be a stock piece (like the one in the lead photo to the left). There were two different belt widths on Flatheads as well as different offsets from year to year. Blundell offers pulleys for both narrow and wide sizes, as well as different offsets. Tell them the year of your engine and they'll get you the right part.
