Re: Issues with rear brakes
#3, if it was rubbing I'd expect a bright spot unless there was so much friction it heated up and turned the metal at 3 blue/purple?
#2 should get hot, but not so hot the friction surface of the drum starts to get blue or the friction surface of the shoe changes color, looks burnt or cracked (if that is the case the shoes are junk)
the brake pulsing at low speed is the evidence drums or axles are not round and true, is there any visible evidence to show any rotational difference, like rubbing that is only on part of drum circumference?
if the issue is axles are only slightly too short a small machined true on both sides spacer between drum and axle may be sufficient. it wont help if the axles are out of true. Don't use 5 flat washers except as a test, 100% chance you will have a vibration.
Tip: later year 3rd gen camaros had a 1/16 rear wheel spacer from factory for some reason. it will fit between drum and axle. (and it will let you run 3rd gen camaro drums on a 2nd gen s10 - barely and with some rubbing at 3 in hard corners - while you wait for the new s10 drums to be delivered)
It is sounding like guy1 had some tolerance issues he tried to fix with the grinder, if he was paid to deliver a fully working shortened rear end he failed
