Because the rear brake line isn't connected, the brake lines haven't been bled and shouldn't be used. I'd finish this out but I really just don't have the time to finish this. It's likely as simple as purchasing the larger steel nut for the brake line and re-flaring it to fit. As for the engine, it hasn't been turned on since like December. It would need a battery. So, turn and drive right now isn't going to happen.

I'll see if I can dig up a battery and check all the fuses, etc to make sure she's ready to drive.
