Jeep/Buick V6 Exhaust Heat Riser Valve Vacuum Actuated 225/231

Description

Lot of 2 heat riser valves.  The vacuum actuated valve works and the other one shown is free and the counterweight swings but it does not have the spring or valve plate (best used as a spacer).  I cannot remember exactly which Buick V6 manifolds these came from.  I believe the vacuum one is from a Buick 231 and not a Jeep 225.  I believe the one that is non-vacuum came from a Jeep 225.  Really not sure which is which so please use measurements and be sure it fits before purchasing as there are no returns accepted.  FAST SHIPPING!
