Need to get rid of the pumkins in the back ... looking at the small silver bullet LEDs ... wanting to put them on the back fender chrome strut on the middle bolt ... any idea on which one would work? They have:

L.E.D. Universal Silver Bullet Kits with 5/16"-18 Mounting Bolt
or
L.E.D. Universal Silver Bullet Kits with 3/8"-16 Hollow Mounting Bolt

anyone do this or know which one would work?

Thanks, Kevin
