Ok, I'll take pictures and do a mini build thread as I go. I was hoping I could see how some other people had done it because I always over complicate things like this.
This is how I did it with the master cylinder behind the cab. It works out great and I haven't had any problems with it.
You can see in this picture that I used the original '41 Chevy brake pedal and made a bar that goes through the back of the cab to attach to the master cylinder.
Yeah, plugging away when it's warm enough in the shop. I've actually got quite a bit done this year. I hope to have it running under it's own power by July 4th. As soon as the master cylinder mount is fabbed in, I will blow it all apart and do some welding on the frame and start putting it together.
