Having seen a few pics of your garage situation I thought I'd add some of my own. I'm not moaning just explaining why my jobs take a while. As my wife says 'nobody is making you work on old cars'. I have done most jobs on Zs including welding inner wings, chassis legs, replaced floor, resprayed engine bay, rebuilt engine, 5 gearboxes incl S14 mod, complete suspension swaps etc etc bear in mind I was doing trackdays for 10 years. Currently I have my heater out and most of the wiring - bear in mind I can only open the drivers door and even that's very limited! My welding was done with 5' high Oxy-acetylene cylinders mostly in this garage. I remember going to 'racers' first house when he was racing his 240. He didn't even have a garage - just a shed for parts!
