This is used aluminum intake manifold that will accept any of the HIF type SU carbs.  It came on the A+ Mini and Metro 1275 engines with the HIF44 1.75 inch carb.  It will fit any Mini motor of any size or year.  It separates the intake from the exhaust (most Minis came with a single cast iron intake/exhaust manifold, so you need a stand alone intake to run a header).  <p>

If using an an HS4 carb, it will fit on the two diagonal studs (along with the required abutment bracket and spacer) using either the 88G429 four stud gasket, or the proper AEC2083 for the HS4.   Not always available used, see C-AHT770A for the new aluminum manifold. Pre-Owned.
