Utilizing the Petrol throttle pedal/cable was something we considered.
I did carry out a detailed inspection of a forum member's LPG Mk6 two years ago but the lack of availability pre-used and the cost of a new Ford part resulted in us producing our own. The Ford petrol throttle cable was unsuitable for our needs and the use of the Ford pedal required the bulkhead to be drilled in an area that would have required dash removal to accomplish, (on right hand drive vehicles at least). Consequently we felt that an alternative pedal assembly provided a simpler installation.
Our throttle pedal assembly is constructed from a number of different parts and can be assembled to suit both left and right hand drive vehicles, doing so helps to keep production costs to a minimum.
Once again Mr V184, I say that you do not appear 'dim', but your eagerness to comment on matters you clearly know little about is in keeping with the majority of your posts!
