Default 1-Piece Front to Rear Brake lIne

Any pointers from those that have done it?

I will need to unbolt the rearmost sub-frame connector point (front is welded). Otherwise I think it should go smoothly based on the web pictures. Awaiting it's arrival now.

PS: The bend over the front sub-frame under the master cylinder looks like the first section to snake through............ and the rest should "nest" well.

You already have subframe connectors installed? Are you going with the OE sized line or a 3/16" line?

I have subframe connectors installed and it makes getting the line as it crosses from the outside of the front subframe inwards towards the center of the car a MAJOR pain. I went with a smaller 3/16" line since I use disc brakes in the back. That made things a bit easier to work with. In my case because my subframe connectors double as the leaf spring supports I wasn't able to gain any clearance there. It requires me to snake everything through that passage at the back first, then through the firewall up to the master. I had to unbend and rebend several sections of line as a result.

From factory line out, to replacement line in took me about 3 hours with the car on my lift. Without a lift it's going to be pretty difficult unless you can gain a good amount of clearance from the subframe connector.

Yes, frame connectors have been in a long time now. It looks like I can "drop" the rear half some to snake it between the floor pan.

Yes, 1/4" stock size line. Manual disc/drum setup.

I run a rear coilover, ladder bar setup. It looks to be a PITA but we'll see. I can see the need for unbending/rebending probably, as you said.

The line finally got rusty internally and clogged after 55 years.
