That's everything I've got for 1986.
Now with regard to championship results... I've yet to fully find out what points scheme was used for the 1983-86 ATCCs. From what I've worked out so far it looks quite convoluted. I don't think what I've worked out is quite right, so if anyone can come forward with more info (say, a description of how points were allocated, perhaps from a race programme or a CAMS manual?) it would be nice
If it helps, I think the AMSCAR Series used the same points structure in 1986.
