we know a few people over your way and for my sins im a tool maker at peco!
yeah its pretty manky out down our way too!
more than anything patience is the key coz you can do the learning while you wait!
ill see if i can dig you some info up.
stuart's manta is only running off mega jolt and individual carbs(a much cheaper way of doing it and much easier as theres around a 1/4 of the wiring involved) hes done away with the injection side of things so realy its just mounts, wether youll have to do much with the driveshafts etc that'll be tricky,
most other stuff exists or can easily be made, (throttle cables pedals exhausts and stuff like that)
