The vacuum plate mounts between the carburetor and the intake manifold and supplies manifold vacuum to the Columbia shift mechanism. Columbia’s supplier catalogs it as the manifold spacer; most Early Ford guys call it the vacuum plate. Same part.\u003c\/p\u003e\n\u003cp\u003eUnused, and still sealed in the oiled paper it was wrapped in decades ago. Three-bolt Stromberg pattern — the rectangular flange with one corner clipped — so it sits under a Stromberg 48, 97 or 81, a Chandler-Groves, or a Ford\/Holley 94. Columbia cataloged one plate for 1935 through 1941 because the carburetor changed a few times over those years and the flange didn’t.\u003c\/p\u003e\n\u003cp\u003eComplete Columbia units trade well into four figures, and it is the controls that are hard to find, not the axle.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES \u0026amp; DETAILS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e✅ Vacuum supply plate for the Columbia two-speed axle, mounts under the carburetor\u003cbr\u003e✅ Three-bolt Stromberg \/ Holley carburetor flange pattern with the clipped corner\u003cbr\u003e✅ Two throttle bores with an integral vacuum takeoff nipple\u003cbr\u003e✅ Cross-references to the Columbia B-49 \/ B-49K manifold spacer\u003cbr\u003e✅ New old stock, still in its original oiled wrapping paper\u003cbr\u003e✅ The Columbia was a dealer-installed option rather than a Ford production item, so no Ford part number applies to this piece\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFITMENT \u0026amp; APPLICATIONS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eColumbia two-speed axle installations on 1935–1941 Ford and 1939–1948 Mercury.

A three-bolt plate of this type was also used to pull manifold vacuum for other period accessories, so confirm this is the right piece for your installation.
