The rear.
In this pic you can see that I have unbolted the brake pipe splitter and cut the mouting bracket off the bulkhead. The pipe was later re-routed along under the floor rather than down the top of the tunnel. What you can't see here is that the FICD valve fouled the handbrake cable where it comes through the bulkhead. This required a change to a floor mounted handbrake. For that I used a Datsun 1200 lever and 710 cable.
