I don't have any picture yet, but ill be out in the garage tomorrow and will snap a couple pictures. I had to use some square steel to make a mount and raise it up about 3 inches for everything to work the way i wanted it to. You could mount it straight to the center tunnel but there is already a lot in the tunnel that i didn't want to work around. I drilled two holes through the firewall for the cables to go through and then ran the cables over the engine mount bar. If you buy the lokar kit, make sure to purchase the rear wilwood clevis kit as well or else it won't work with the rear calipers on the 914. The only modification besides the mount for the brake handle, was cutting the little end off the cable where it attaches to the clevis. The cable has a ball on the end of it with an extra piece of metal on the end. This straight piece of metal needs to be cut off in order to fit in between the caliper arm and clevis. The little extra piece of metal can be seen in the picture below. Cutting that piece off does not affect the performance of the e brake. I was worried the cables would fall out or come undone, but they did not and everything worked out really well.
I have no idea if you could use the stock cables, you might actually be able to do that but the cables that come with the kit work just fine for me. The holes i drilled were straight behind the e brake mount, just above the center tunnel and the fuel lines. My lines are not run through the center tunnel, but above the center tunnel inside the car.
