66 Satellite disc conversion firewall brake line confusion

[DCDP]

I'm doing the PST front disc conversion on my 66 Satellite using my original spindles. I'm planning to use a 67-72 proportioning valve where the junction block was. The problem I have is getting new brake lines. I've been looking at pictures people have posted of 67 GTX's and others and it seems like the line to the right brakes goes over the steering column under the booster. My car has the right brake line going down the right side of the steering firewall opening. The fittings are two small to use as is. I'm assuming I'm going to have to do something different? Was this standard for 66? Options from vendors have a straight across the firewall, or 4" rise over the transmission for 67. Factory 361, A/C, PB car.

I don't know if this will answer your questions, but I have a '66 Satellite and I have some experience with the brakes.

The original brake line for the front passenger brake went straight across the firewall, then turned down to join the 4-way junction block on the frame rail. The block had an input line from the single-piston master cylinder, then sent one line to each front brake, and one line to the rear brakes. My factory parts all use the same 3/16 lines and fittings that I used for my Wilwood set-up.

Inline Tube makes a 2-channel junction block that replaces the original one. The bracket is the same as the old one and your factory 3/16 lines should thread right in. The difference is that it keeps the front and rear circuits separate. So you will need to run an additional line from your new master cylinder to the new distribution block (either front or rear). If you go that route, you can install the proportioning valve at the master cylinder and you will only need 2 outputs from it (front and rear).

I ran that distribution block for a few years, but I have recently re-plumbed my entire brake system. My Wilwood proportioning valve has three outputs, 2 front, one rear, so I now have everything plumbed directly to the proportioning valve.
