Triumph Pre-Unit STAINLESS Engine Bolt SET 500 650 54-on BSA Drive Exactly the same design andPerfect and lovely, to suit all swingarm Triumph from '54 '59, I believe. These are the bolt assemblies that hold the engine into the frame plates. Exact copies of the factory hardware, and fabricated in rust free, tarnish free stainless steel. Part numbers are labeled and a copy of the factory fitment schematic are supplied. Supplied with thread lubricant. A kit to suit earlier rigid frame is also available in another listing.
