caddy mk1 fuel tank where to get one

hi folks not been on the forum for a while ,got my campaign resto finished,purchased a caddy looking for a fuel tank or even info on where to get one? were they made just for the caddy ? any info would be appreciated thanks all

Hi mate- Fuel tankls were Caddy specific.

I think VW Heritage had them and also Just Caddys
