Is there a diagram for all the holes on the firewall for B-bodies, specifically a `70 road runner, I`ve seen them for E-bodies?
Shouldn't there be a hole for the engine ground strap?
Not on the firewall (probably wouldn't hurt to add one). For 1970 the engine ground was part of the negative battery cable and attached to the rad cradle.Shouldn't there be a hole for the engine ground strap?
I'm curious about your hole marked out for the Clutch Safety Switch wire........was that a factory hole, or did someone drill that one out ? I have not seen that before, and there was a thread about that earlier in the week. '70 RR firewall hole ID
I believe that was used on '69 and prior.Shouldn't there be a hole for the engine ground strap?

On a 70 it is a factory hole. The clutch (neutral) safety switch wire goes through the firewall to the starter relay. You can see the grommet on the switch wire in the attached pic. For automatics it is not drilled and is just a dimple in the firewall.I'm curious about your hole marked out for the Clutch Safety Switch wire........was that a factory hole, or did someone drill that one out ?

The clutch safety switch is normally mounted on the pedal box, and the wire is internally fitted under the dash into the firewall terminal box.
