So I decided to move ahead with replacing the brake lines. Understanding working on things in this car (and any car really) lead to another I just went with the preformed SS lines. I pulled the brake booster and master cylinder and will be replacing the carpet, grommets, and perishables in the process. I asked around about rebuilding the existing booster and was told that some of the parts are unobtainium so either clean up the one I have and leave alone or replace with an updated unit.
I really like the clean setup of the SACC unit but it looks like it deletes the booster and a bit pricey relative to other vendor replacements. I’m sure it is great as I have been impressed with all of Scott’s products but compromises must be made! Plus I need to buy the power steering unit down the line. 😬
