Mechanical tacho drive

I am looking at installing a mechanical tachometer in my Kingswood. The main question I have is regarding the many Group C Toranas run when new, as most of those I have seen photos of seem to run a 'Jones' brand mechanical tach. Where abouts do these cars take the drive for the tacho from on the Holden V8? Is it from the front of the crank, or maybe the front of the cam? Or do they run special distributor add-ons to have a mechanical take-off?
I am hoping that someone who maybe has one of these cars will be able to shed some light on the situation and even post some photos of specific areas?
Thanks guys.

The tach/dizzy i saw came off an A9X that ran at bathurst in the 80s

From what you are saying here, it appears that the twin coil, twin point L34-style distributor made by 'Scorcher' had a mechanical drive on it for a tachometer.
Is anyone else able to confirm this?? How about factory L34s run in circuit racing, anyone else?

Does anybody know when these were first used on the race cars i understand Gown Hindaugh developed them under their name scorcher. HDT used a Mallory item and a Smiths gauge that worked backwards

I bought this mechanical drive M.Mallory tacho from a former owner of the second Patterson's L34, which was converted to A9X specs around Sept '77. Whether or not it was given to Brock by Harry I don't know.
The car it came from is the front one.

I see that the Smiths mechanical tachos are still available too.
