24V Perkins Conversion

Still trying to track down all the parts I require to convert the Perkins engine to 24V. So far I think I have found 24V glow plugs, and apparently there is a 24V starter that will fit the engine, however, it costs £360 and Perkins won't give me the part number so I can't look for an equivalent.. thanks Perkins!

I have yet to find a 24V ESOS as pictured below, however, I could run this from a 12V regulator if need be.
