I need a longer bolt for the axle vent 8.8" rear end. I put longer aftermarket lines on and the rear one has a thicker block so the bolts not long enough. Any idea who has a longer one or what anyone here has done for the same issue? I've checked hardware stores and auto parts stores with no luck.
I have not heard of this before.
My guess you may need to make one.
Find a bolt the is long enough to go thru the block and still have threads out the top when screwed into the axle.
You will need to drill it down the center for the gasses to go out.
Because it was long and has threads out the top you can put a nut on to hold the block to the axle.
Cut the bolt head off or grind it down and slip a hose on and run it up to the frame and you are done.

Get a piece of thick metal or thin metal with washers, that will be the same thickness as the original block. Bolt it down to the rearend with the original vent bolt, and then use a regular bolt to bolt the new block in place. Like this.

I thought about that but it seems like to much of a pain without the proper setup and I don't think my 30 year old press will be good enough.
Sorry, but I con't understand why you can't find a longer bolt or even a longer one that you use washers to take up the slop. Bolts come in 1/8" length's up to much longer than you would think. We used to have 14" long bolts at work.
You should be able to get the correct length. Have you tried McMaster-Carr ? I can't imagine the bolt you need isn't easy to find, or am I missing something, like this is a one of a kind bolt ?

It is not a regular bolt. It is a hollow bolt with a hole drilled through the middle of it, and a hose nipple made on the end for a vent hose to connect.

Oh, like a banjo bolt. Earls may have a banjo bolt that has a nipple.
Look at the picture DaveF posted in #3
He is using the same vent nipple from the factory to hold flat stock to the axle housing.
He is using the flat washers as a spacer to fill in where the brake line block would be and tighten down the nipple & flat stock.
The other end of the flat stock has a hole. You will need a nut & bolt to go thru the brake line block and the flat stock to hole the brake line to the flat stock and done.
If you have the nipple out of the axle the only other thing you would need to know is how long the flat stock needs to be.
Once you have how long drill holes in each end of the flat stock so the nipple fits thru, stack of flat washers and a nut & bolt for the brake line block. Then you only need to get under the truck to install the flat stock & line.
Like I said it is so simple I never gave it a thought to do it that way.
Good job DaveF

ps now that I think of it dont they do something like that when they do 6+ inch suspension lifts?
Or you could thread the 1/4" flat stock and just use it to tighten the bolt into, then use a good screw type hose clamp to hold it on the axle housing. I guess if you think about it enough, you come up with ideas.

My only concern with this is the metal lines that go into the block. They don't have much give and moving them out of the way enough to do the plate might put them under stress that can cause failure later on. Just moving them half a hole up has a lot of tension, I could probably take off the hold down clips but then they are floating and might catch something. I think I'm going to see about drilling a bolt or put a coupling nut on the OE bolt with a little brass flair threaded adapter on the other side. 1/4 brass flair is the same thread. I tried to find a brass fitting that's long enough but I couldn't find any with threads longer than an inch.

Never heard of brakeline that could not be tweaked or bent a little bit. Not sure what type of aftermarket line system you have, but it doesn't sound very good.
