Sherwod...Was thinking of complete fab for the units.
The reason....the old throttle bodies are so corroded where the butterflys touch the side of the bore, that the gap is large enough to pass air to run the engine at 3500 rpm!
I thought about over-boring the hole to get enough room to press in a silicon bronze sleev, then re-bore back to original size....but not enough meat in the sides of the casting to allow this.
I would have to bore them out to more than 44mm to clean them up and this would be too big for my little 2.0L .
Sooo....new metal all around is the best solution.
As for the sticking...not a problem....ball bearings to float the slide on....teflon to guide the slide....and a positive return for the linkage (gear and rack).
It's not that big a job....the main unit containing the slide...the support columns to the head with the correct flange....and somthing to guide the air in...either horns or tubes to a filter holder.
I have the machine shop...the material...and no money!
I can't afford to buy these things....so build is the only answer....unless someone wants to donate a pair of throttle assemblys....LOL.
