Harley Shovelhead Stock Flange-Spigot Manifold Adapter (1 1/2" Bore, Needs Seal)

This is a fairly simple adapter that mounts directly to any of the stock, flange style manifolds used from 1972-84. 

Aluminum construction with a 1 1/2" bore and a a 1/4" O.D.  Flange bolt holes are threaded for 3/8-16 bolts, but we would still recommend using nyloc nuts on the back side, once attached.

Required is an "O" ring seal with a 1 7/8" I.D. and a 2 1/8" O.D.  Or, a quality flange gasket could be used.
