Intake Manifold Clamp, FX & FL Shovelhead Late 1980-1984 (OEM/NOS #27063-80)
This is the late clamp, correct for use on all FX models from late 1980-84. It is also correct for FL models of the same vintage. For the '78-'79 vintage, a different part number was used. The early clamp featured a solid clamp band. In this late version, the clamp band is slotted. We presume the slot aided in better clamping action, thereby providing a better seal. Otherwise the '78-'79 version and the '80-'84 versions are exactly the same.
You will notice there is no screw or nut. Although Factory Parts Catalogs indicate the screw and nut should be included in this part number, we have seen early NOS packages without them. So in some cases, they were included. In other cases, they were not. And this clamp comes from an originally unsealed package, which we opened for these photos, and no screw or nut were included in this original packaging.
