Tail shaft markings

[Grunt]

Does anyone know what the Holden factory numbers painted on the tailshaft mean?

We found a blue tailshaft for a mates concourse resto HX Sandman and had some painted / rubber stamp yellow numbers L382 of similar, its obviously not a gear ratio or assembky number as the colour of the tail shaft was used to tell the workers what part to use.

Any help would be appreciated

Looks like a '78 date code to me.
I don't have my books handy atm. Byron might though!

Thanks, its a bit specialized, most didnt even know the marks are there

Are you sure of the number you provided is correct? Or just a guess?
Date codes are common on Holden parts but it varies from department to department, so understand and deciphering them can be a little tricky.

"L" should = November.

They had black tail shafts didn't they? Not sure what blue ones were fitted to. Sure it's not an earlier series shaft?

That's why I'm asking if the code supplied is correct.

Does look a bit like it could be M57

[Innuendo]

Well D457 doesn't make any sense.
M57 would
M157 would

I say M because that letter equals December.
The 7 is for 1977.

Can you clean it up any better?
