Thanks Ron, but not quite what I'm looking for. I am building the TB from
scratch for a totally mechanical system - all I need is a set of shafts and
plates (2 of each) It is a "2 barrel" system with the two barrels separated
by almost 2 feet - Soob EA81. I sliced off a bit of the original SOOB
manifold and made a plate out of it. I will braze a peice of oval tubing
(high end patio furniture) on for the coolant passage, and a peice of 1 1/4"
Aluminum Ridgid conduit for the throttle body. That's the basics, the
details are even more fun!! I'm told an 86 - 89 Tempo/Topaz uses the right
peices, so I'll be doing some scrounging next week.

Thanks for the offer.
