Justin, I'm in the middle of redoing the complete brake system on my 40. My brake lines were rusted thru and the rest of the parts like the springs had served there time. I got all the parts except the drums (I turned the drums) for just under $500. The lines I found out are 1/4" dia. and you can get them from Napa. They will cost a little more at Napa than if you get them from Eastwood. the rest of the parts I got from Jim Carter and Chevys of the 40's. It's too bad but you can't get everthing from one site.
Good luck.
Kevin
