Firewall smoothing

What year Mustang?

I am still putting my 66 back together, so here goes. The small round holes are for either the pins holding the interior firewall insulation in place or for the support straps for the wire harnesses. The rectangular horizontal hole is for the engine gauge feed harness, wires from this go to the blower motor and to the solenoid. The vertical rectangular hole is for the headlights harness, one of the round ones (above I think) is for the washer pump feed. The two holes at about four O'Clock position near the steering column hole is for the e brake handle. Best I can do from memory, hope it helps. Jeff

I know what most of the others are, let me know if you are stuck, there are 6 bolts for the master cylinder and pedal support bracket. The gas pedal bell crank mounting and linkage hole are there also. I see the speedo cable hole and e/brake cable hole as well.

A little blurry..but I think this will help.



Left square hole is the heater control wiring, right retanglur hole is for the motor and lights harness

Upper pin holes are for the harness holders

Lower pinholes hold the brake lines (I think)

Heck..Shave em all and make new ones as needed
