Hello Tony,

Love to see your TPS photos as I don't have a manifold to look at.
Your method sounds better than me making new throttle shafts!

I was thinking about doing the flat tops first as they would work
nicely when converted to TBI. It would make use of a carb that might
otherwise be discarded. But if there is more demand for the four
screw round tops they can be done first.

tube portion of the manifold works well to actuate a TPS. There are
some holes there for mounting another bracket relating to throttle
stop, so it's just a matter of using slightly longer bolts and the
appropriate bracket to mount the TPS. It's hidden nicely under the
PCV Hose that way as well...

to a cable throttle quadrant, so the stud approach handles more than
enough torque to function as a TPS actuator.
