This is a 3/16” thick engine and gearbox mounting plate for building a custom swing arm. The slots allow for belt and chain tensioning. For used with big block and v twin engines. Requires welding to an existing or fabricated swing arm. This item is raw steel and can have slight rust on arrival. We leave it raw for welding purposes. Couple this with our gearbox mounting bracket for use with these gearboxes.
