Well, the hoist is installed and today the gearbox came out. I can't believe I was able to remove that huge gearbox by myself, I'm glad I got a transmission jack when I bought the hoist now.
I managed to fit up the 6spd to check clearances, I was happy to see the 350z mounts bolted straight up to the stock holes in the floor, and all the engine bolts were right, other than the starter motor holes being out. (due to the turbo) I will have to drop the engine to fit the 350z sump now, no big deal. The starter will have to be relocated to the drivers side.
The gearstick hole doesn't line up, I will have to trim it an inch or so longer.
I have found some more parts through Nuwan, apparently the brake booster is smaller on the manual to accommodate the clutch master so I have a clutch pedal assy with master, a brake pedal assy with booster and clutch line coming soon. Still searching for the handbrake and console, they will most likely have to come from Japan.
