Shaker cable hole

What is the size of the hole for the shaker cable grommet on the firewall?

I can check mine tonight, but I would recommend you scribe the circle, then drill it a little undersize and use a rotary file or hand file to take it upto the scribe mark.  If you try to just drill it with the right sized hole saw, it will probably end up oversized.

Thanks for the tip.

Looks like 7/8" ( 0.875 )
