I have replaced the floor of my 1963 Beetle and am now having difficulty setting the accelerator pedal in the correct position. I have bought a new pedal and linkages etc. but the Z shaped bar is very loose where it connects to the lever resulting in the pedal leaning over to the RHS when depressed . As a result it is not possible to get a smooth operation. Any help would be appreciated.

you have the pivot point in the wrong position

Thank you-- but by pivot point , do you mean the position where the pedal is connected to the floor and if so what is the correct position? Thank You.

yes that position you will have to measure it of another car
