You need them from a 6-cylinder car. Other items you will need to change during the swap are: throttle rod linkage, the 6-cyl models used a cable in 69, also the fan shroud will need to be changed, but you could modify a small block one to work as the 6-cyl shroud is very hard to find. Why are you changing to a 6-cylincer from a V8? Any particular reason you are not using the 250 instead of the 230? ...................RatPack...............
