questions about electical underhood stuff

thanks guys, I think the previous owners came from "Billy Joe Bobs House of Car Repair, some of the stuff on this car is unbelievable.

It had a feedback carb on it, with no Lean Burn, motorcycle mirrors, when the tag says it has the Racing Sport Mirrors, i changed the Idler arm yesterday, one side had two small zip ties through the cotter pin hole, the other had a small wire, tied in a knot, SIGH,

The good thing is that the engine, trans and rear dont leak, it goes straight down the road now, and the car runs fairly good now, it still needs some carb work as it has a stumble when you give it gas, even though i rebuilt a BBD carb from a 73 Truck, probably the bushing thats leaking, and needs a new alt, i think the bearings or something inside is worn out, its making a weird noise.
