sorry, don't know anything about your car, but I have some trivia related to it.
When I initially saw the number plate, I thought "that's a bit too late to be original", but looking at the Vicroads website, the list shows the first plate issued in 1969 as KEB 500, KAM isn't long before then, so you'd assume the car is late '68 - which I'm sure you know already
Vicroads issue their plates in batches to the local offices, each office gets a whole heap of plates, and it can take the small offices a long time to use up their current stock before getting a new batch. I'd reckon in 1968 it could have easily been 6 months for a small office to use up their stocks of J**, before getting the K** series. So I think it would be safe to say that your car would have been registered at a Vicroads office that had a high turnover of plates, so would most likely have been sold by a big dealer in Melbourne
here's the Vicroads link ->

also, keep that detail in the back of your mind for when some 'expert' says the number plate is too late for the car to be the original rego.
It's gotta be the original rego, so please keep the plates on the car, don't get a personalised plate, and keep the actual plates, because the re-issued ones we get these days don't look right. If the plates are ratty, just repaint them yourself
