IVR pulse at 4 volts gauges read low

he's politely telling you that the old regulator parts have to be removed completely , the "thingy" that is bent out of the way has load of it's own in the coil of wire around the bi-metallic piece and cannot be safely left in there to bounce around contacting the remaining internal pieces of the guage .That is what I was saying in my post as well , you may also notice that the terminals and "Thingy's" are not mounted to the metal housing but the wafer material I also mentioned in my first post , this stuff is very very fragile almost like a soda cracker after 45 years or so eh making this work like brain surgery .
