Accelerator pedal

Hi, my beetle, 1303 RHD has only the roller for the accelerator pedal. There is no hinge for a pedal fixed to the floorpan. what parts would I need to get to restore the original style of pedal? I have looked and found many parts and repair kits but I dont know which bits I need. The seller told me that the floorpan was replaced eight or so years ago. I can see that there is a depression in the floorpan where a hinge could be welded but what other springs and pivots do I need?

You may also need the plastic roller. Rest of the parts are on this page.

You could drill two holes in the floor pan and bolt the lower hinge in place.
