This is a secondhand pedalbox (pedal box), complete with pedals and hydraulics, for a Jaguar Mark I, II, 3.4S or 3.8S saloon. It's just the thing for converting an automatic car to a manual transmission. The picture shows a representative assembly. All the parts are present for rebuilding, or you can replace the hydraulics with new parts.
We prefer to send secondhand cylinders out to be sleeved in brass or stainless, rebuild them with new rubbers, and then they are better than new.
The picture shows an assembly for a left hand drive (LHD) car. We often have a set for right hand drive (RHD) cars, available at the same price.
