1969 Firewall hole size needed.
« on: March 26, 2024, 04:10:11 PM »
I am looking for the diameter of this hole in the center of the firewall.  The under dash main harness with a grommet and wires for the wiper, engine gauge feed harness and others pass through here.

Regards,
Scott

I would assume that is for underdash harness, 14401, and if I got to punch a feed thru hole for any harness, I measure the diameter of the grommet's groove and use a chassis punch.

Not why I need it.  I need to verify the original dimension.

Scott,
If nobody else answer before I get out to the shop this afternoon and slide the harness out. I'll let you know.

Sorry Scott I couldn't get the harness out to measure the hole for you.
