Called fine line tube, which happens to be closer than summit to me. Said they sell everything but "AN Intermediate tube" "which goes from front to back"

TRA0801SS - 07-10 GM 2500HD/3500HD with 6.6L or 8.1L non-Dually Rear
Axle Brake Line; Stainless
~$58.00 price point wise.. think these are the lines that actually mount on the rear axle and not ABS to rear axle

TKT0705SS- 07-12 Silverado/Sierra 2500HD/3500HD, W/O Code JL4, Front
Brake Line Kit; Stainless
That one doesn't show up on their website.. TKT0705OM does for 130.00

Good new would be I only have to make 2 of the 6 lines

I wasn’t able to find the rear brake lines or the ones on the axle for an LMM with 4 channel abs earlier this year. Luckily all but one on my parts truck were mint.

00-07 also had sae hardware. 07.5+ went metric. I ended up using some nicopp line to make the one running to the front passenger wheel.

I think I can get lucky for the front axle, while definitely time consuming I'm better off redoing everything including rubber hoses..
The ABS module is going to be a PITA, after lines broke, I just cut all of them above the nut.

Been working on a shopping list of parts. And trying to get a reasonable order of things to go back together. Currently body is just sitting on the frame. Probably pull it back off to run the brake, fuel and electric stuff

Haven't quite figured out how I'm getting middle body mount bolts out yet either.

I bought a new abs pump on amazon warehouse deals for $90 earlier this year. Came in a beat up box, but it was brand new. You will need to salvage the mount for it tho, along with the mount on the rear of the frame that the two hard lines go to as they seem to be unavailable. I had to sandblast and paint mine.

If the ABS mount is that bad, Let me know... I am almost positive the bracket is the same from the 1500's... If not, I can always go shopping for you. We don't have the rust issues here...

I recall there being different plugs between 2 different manufactures of the electronic modules. I tossed the manifold on the one in the crew cab but kept the electrical portion because I already have 3 from extended cab 1500 GMT800 trucks... But it's funny because I couldn't even get $150 when I tried to sell them. Only had 1 guy but he had a different module... I think it was Kelsey Hayes and Bosch that manufactured them. If I recall the $150 is what the parts houses wanted for a core at the time.

Should be able to re use your module. It just bolts on.

Nice... I can't believe what the salt does to all that stuff...
I would have fought a lot hard with lines and cab in the way,
tapped a socket on it and lit it vibrate for a bit.
Got stuff to put on this engine as well. Pulling the charger, saw a lot of stuff laying in the valley.
Some of that will wait till truck is paid off.

How hot can I get the torsion bar area of the A-arms before causing damage? PB blaster has found a way through the mount.
I de-scaled vast majority of it.
Do have long barrels air hammer and 4lb sledges
