The 69 assembly manual, the section covering the std. and HD Rear Axle Brake Pipes, page 65, calls out this bracket as P/N-3954381. Below is a picture for reference. It also shows another clip P/N-3956700 securing the RH pipe at the first cover bolt just past the 12:00 position. As attached a pic. These two items were original on my 69Z. Bracket 3954381 was not painted, rusty and pitted. I ordered a repro #BR-8 from Rick's 1st Generatation, now priced at $15.99.
You may also need the bracket P/N-3953281, that holds the flex hose to the underside of the body, at the point where the flex hose interfaces with the steel line hose. Ref. Rick's 1st Gen. #BR-35, $25.99.
Its been noted that Rick's 1st Gen has changed hands and prices have taken quite a jump. You can visit: www.rickscamaros.com, or contact them at 800-359-7717.
JohnZ....are these bracket not common among all 69's?
Thanks for the pics. I was looking for information on the bracket that mounts the flex brake line to the differential. In changing from my 8.2 rear to a 12 bolt, my old mounting bracket from the flex hose does not work I also have the metal strap as shown in your last pic. Your second to the last pic, is that from the front of the car hard line back to the flex hose? I am waiting for my part from NPD. Have used Rick's in the past, but have seen a lot of posts on their issues. Just trying someone new. Thanks again.
