What are the round holes on the right of my firewall.

Jonboy · 08-11-2011, 04:51 PM

The top one is for the wiper motor (the large one), the one towards the center of the firewall is for the speedometer cable, and the lower one is for the e-brake cable. I think.

J/D/S · 08-11-2011, 05:13 PM

E brake comes out of the bottom I belive.

Rogue_Alphonse · 08-11-2011, 08:11 PM

Is it a standard transmission cab? The lowest hold could be for a Z-bar clutch setup. I really don't know, but I'll find out when I convert my auto into a Z-bar setup with a Muncie

Well now that those questions are answered, where's the rest of the pics.

Show it of a little
