Need help to confirm fitment of brake hard lines from Inline Tube

[RayL]

'73 Challenger. Front disc, Rear drum car.

I planned to replace the rear brake lines from the combo valve out to each rear wheel cylinder, including the flexible hose and (broken) axle bolt.

Inline Tube has the short hard lines that go from the flexible hose tee on the axle out to each wheel cylinder (Item DEB70R1). BUT the description says "1970-73 Mopar E-Body Rear Axle Brake Lines 8-1/4" Axle 2pc, OE Steel". My car has the 8-3/4" axle, 489 case. I called Inline tube and was told these lines should fit based on some description they have but is not seen on the site. "If yours looks like the picture on the site, it should fit". Okay...

Then I ask for help finding the long hard line that goes between the combo valve and the flexible hose. Was told that it's not available as an individual item but is included in kit DEB7307 "1973 Dodge Challenger Power Disc Brake Line Kit 7pc, OE Steel". The kit includes the same short lines sold as DEB70R1 for the "8-1/4" Axle.

Can anyone confirm that these lines fit a '73 Challenger with an 8-3/4" axle?

I don't mind buying the kit to get the long hard line. But I've been getting beat up on parts lately (poor quality, wrong, etc...) and want to be sure what I do purchase actually fits my application.

Thanks!

I can't help you directly with your question, but I can say I bought fuel lines from them that fit very well. 
Your links just send me to a google home page?

Hey dodj, thanks for the reply. I have also purchased from Inline and was satisfied with their products. In this case, they are not clear if these lines are correct for the car. So I thought I'd reach out to the Mopar community to see if anyone had experience with them.

I (hopefully) corrected the links.

  no experience myself but looked at Right Stuff site & they do have 2-different rear axle lines ..  7001 for 8 3/4 & 7002 for Dana
 pictures are generic so no indication of real shape

Bullitt- good to have options. Thanks!

My comments may or may not help. I recently went with Inline Tubes brake lines on my 72 Challenger. I also bought the new proportioning valve. The new proportioning valve created problems on the engine bay ends as it was not an exact match to the original one so I had to adapt on that end. The line running from the engine bay to the 8-3/4 axle was a perfect fit. Only very slight tweaks needed as the line comes folded for shipping. The line from the axle T to the passenger drum was a great fit with almost no tweaking needed. The line from the T to the driver's drum was not exact and required more tweaking than I was comfortable doing. I made a new line from a brake line kit I bought and had no problems. As I said, if I had used the original proportioning valve, it would have been a great fit of the lines in the engine bay.

71vert340 - thanks for the feedback. Good to hear the long line works without much trouble. I'm going to order the complete kit and just deal with it as needed. This work is all part of a Hydroboost upgrade. I'm also replacing and relocating the combo valve and installing a line-loc. So I'm in for a lot of tweaking!

Thanks,
Ray

I would recommend spending the few dollars and buy a brake line kit that includes the tubing, cutter, double flare tool and fittings. I bought mine off Amazon along with a tubing bender for avery reasonable price. I remade the two line from the master cylinder to proportioning valve.

71vert340 - Great tip. I have the flaring tool kit and an assortment of fittings from previous work. Seems I'm always missing the exact fitting needed for some reason, but my local Napa has a good selection. As far as making lines, I found there was a learning curve when working with nicopp line. The flare can be easily distorted if you don't prepare the tubing ends properly. I watched a bunch of YouTube videos and got the process sorted out before making any lines.
