Is the rest of your system original or older than 15 or 20 years. If so, get a complete set and replace it all. I made the mistake of just replacing the rubber hoses, and when the fitting that connects the center rear Tee to the hard line from the prop. valve wouldn't let go, I had to cut the hard line. When doing so I realized how weak the original 40 year old steel had gotten. I would have saved over about 75.00 if I had just gotten a set from the start.

 

If we knew the fitting sizes and it's what we have (or can get), we might be able to make one up for you. It would have the ends then, but would not have the mounting bracket that's part of the assembly.
So it would not be stock, but might at least get you there and back.

The best action would be if the other vendors that make the proper part will be getting more in soon. But if they don't know when, you might be out of luck for awhile.
We make our own for the '66 to '77 Broncos (https://www.wildhorses4x4.com/produc...co_Brake_Hoses) in both rubber and braided stainless, but as you can see by the pic there is no mounting bracket on those vehicles. Bolts straight to the frame, bolts straight to the axle tube (with the breather bolt) and that's it.

Be great if it was the same tubing size of course. But I'm not holding my breath at this point!

Good luck.
