Looking for a good one with the flapper (heat riser) that works and isn't so loose the thing leaks like the one I have which also has a frozen flapper. I'm also looking for the throttle linkage fulcrum (bell crank) for a 3100 truck. It should only have the two holes for the linkage and the pivot holes. I think the three hole version is for the powerglide model or a car linkage.
