Continuing with Peter Malinson’s remanufacture theme, attached is a photo of a “new” Plus 2 jack complete with pin to engage in sill socket. Even comes (pre-mod at least) with “TUV” approval!!!
Great stuff Gerry 
Are you going into production or is this a one of for personal use ?
Peter, no plans to go into production. But sure works a treat for me as a road side jack that works with sill jacking points. Much easier to use for a tyre change application than jacking under suspension etc.
Weld a 1/2 drive socket to it, then you can run it up or down with your cordless impact.
…or you could knock up an adapter plate for yor boot which will fit a bottle jack,trolley jack or whatever…
