Thought I should poste where I ended up. This is the Summit throttle return, the Holley TH350 kick-down cable mount, Spectre (I hate their stuff, but it was handy and cheap
) throttle return spring bracket and a custom-cut throttle return spring from NAPA. Works well, looks safe - only a single spring, though...
I suspect I'll pick up the really nice Holley or Lokar bracket sometime in the future - likely when I transfer this engine to the soon (?) to be restored chassis.
Yes, I know about the frayed water temp sender wire - fixing it now
