Tacho drive

[Clumber981]

I want to keep the 'Vague-liar' tacho on my SFC1000.
I however have a 180 type cam box cover as I'm using reprofiled cams with the cam drive on LHS of camshaft (as opposed to RHS for RGA and SFC1000)
I have an ND denso drive pin (with 'spade' at one end and the squeezed tube at the other to take the square tacho drive cable) which I thought was what is required but
it is too long and I end up with a big gap between the knurled nut on end of the drive cable and the threaded boss on the cam cover.

Can any one point me at the correct drive for the SFC/RGA?  I can't see it on Wolfgang's part list.
Am I doing something wrong..  I'm assuming there is a different drive piece available for these models or is it something more drastic?

Any help/advice much appreciated.

There is no spade on the SFC/RGA tacho drive the inner cable fits straight into the rev drive, recon you need to shorten the inner cable by the required amount and have a new square swaged on the end, you might be really lucky and be able to use a 180 inner in an RGA outer if not Venhills should be able to do the swaging for you.

Thanks Keith , so that means the drive itself is correct ie having a slot, but the cable just needs to fit straight in, no adapter like on the ND?
seems a recipe for short life but heh hoh.

The drive should have an internal sqare, not a slot.  Square cable end fits in snugly.  Gives no trouble at all if everything is correct.

I came across that problem when I fitted a SFC 1k cable to the Veglia and S1 cam cover. Couldn't work out why before realizing I had a custom made cable when I first fitted the Veglia.
I ended up making a spacer out of ally the the cable outer fitted into and clamped to the cover using the nut as per foto. Was done 15 years ago so the cable is looking passed it useby date.
Have a new cable to fit, just need to make another spacer or butcher the existing cable to salvage the spacer.
