The deceleration dashpot in my '65 Skylark (300 V8 4.9L with Rochester 2GC) does not seem to be the right fit. (The plunger arm appears too short.) I want to compare it to a known-good part, but can't find anything in the stores. Does anybody have a photo they can post of their part (for my exact car) so I can better figure out whether or not my ancestors put the right replacement in decades ago during a roadside emergency?
