The six had the same clutch as the 9.5" optional one. The 9.5 optional clutch was the same for petrol and diesel fours as well as being standard for the six.

Your flywheel probably is drilled for the three dowels as well as for the two dowels, so you could convert to a 9.5" clutch. (dowels are 502116)

Hope this helps.

Thanks John,

The original plate is definitely 9", is it possible therefore that the 9.5" plate could also be fitted....?

I will certainly check to see if there is provision to fit the diametrically, two pin arrangement, but then if that is the case I will have remove the two, now obsolete dowels..?

Thanks again,

Norm.

Ps I reckon the vehicle was made about 1967, but it is not the original engine..!

If the flywheel is drilled for the three dowels, no problems should arise.

If you fit the larger clutch, then the two pins for the 9" clutch will need to be removed - I have never noted whether they are on the same radius, but I assume they are not.

Hey John,

Checked the flywheel and does look as though it is drilled as per your advice.

but what I can't believe is that they have the dowels in stock in Melbourne, so I should get get them tomorrow.

So well done mate, you've saved the day.

Thanks again

Norm.

Norm, Did you paint your head and block?

Norm I am assuming that by now you have sourced head bolts and got your engine back together. On the off chance you are still chasing bolts I know that some people source bolts for Holden engines from Cat.
They may also have the correct size bolts for your needs.


Cheers, Mick.
