My Garage
Firewall Hole ID

Got a PM asking for the decoder ring to a couple photos I did. This is based on a 68 S code manual GT. Could not find the original post.

Any corrections or clarifications appreciated, can amend the list if needed.

A – Power brake booster, red (manual cars use only two side holes on booster, bolts thru other with plate on firewall)
B – Steering column – 4 sheet metal screws
C – Washer hoses (small hose on top)
D - Engine feed wiring harness
E – Speedometer cable
F – Clutch rod (blank not punched out on Automatics)
G – Emergency brake (also clutch spring return bracket on manual cars)
H - Accelerator pedal grommet
J - Accelerator bell crank – 3 sheet metal screws
K –Brake line clip
L – Fuse block, 2 sheet metal screws
M – Unsure – not used on either of my 68 S codes or 68 C code, maybe 6 cylinder use
N – Pedal support to firewall – 2 sheet metal screws
P – Brake Line Clip
Q – Alternator Wiring Harness / Transmission Neutral Switch Harness
R – Firewall Pad Retainer
S – ??? (see pic next post)
T – Heater – 4 studs w/stamped nuts w/sealer (heater equipped cars only, not A/C cars or heater delete. For A/C cars oval plate to right is punched out)
U – Heater Hoses (on all cars, for A/C holes were capped with rubber plugs)
V – Brake line clip
W – Firewall pad retainer
X – Unsure, think it may be dimple for 6 cyl accelerator rod bracket, not used on my V8’s
Y – Heater motor shield, used on A/C cars and left on many big blocks
Z - Engine ground strap
