Gogar,

Does you car have a hand throttle between the seats? It looks like the heater lever but is black and will be on the left side of the handbrake.

Also, be aware that the 73.5 engine has some items that are unique to that engine.

Good point it isnt hooked up soooo! oops should have read a little farther.
