Actually, this should be fairly easy to research: Bear in mind that Chevrolet chassis 1955, 56 and 57 are for, all intents and purposes, identical. If one digs deeply enough with Google, even eBay, one ought to eventually come up with say, a lubrication chart from a shop manual, which would show almost all those details. In addition, Chevrolet (and probably the other automakers as well) had a habit of suspending an example of their cars suspended on end, for the purpose of taking photographs of the entire underside of the car.
I would suggest Googling for message boards which cover "Tri-Five Chevrolet's", and register on those, ask this question of the people on boards like that--I would bet that in fairly short order, someone will post up a pic showing what you want to know.
