Wanted - Brake Piping Junction Blocks

Hi fellow Patrolees, looking for a part for the Patrol. I'm working on replacing the brake lines and hoses, and two of the brake line junction blocks (the parts manuals call them "connectors") are damaged. Specifically, the internal inverted flares in two of them have been damaged (pretty much wiped out :o ) by severely over tightening the flare nuts.

The Nissan part number is 46313-25661. The best I can tell from the parts manuals, these were used until the early to mid-'70s, possibly until the dual circuit master cylinder was phased in. Each Patrol would have four of these -- one at each front wheel, one where the flexible hose connects to the front axle, and one where the flexible hose connects to the rear axle. Note, there is another that looks similar but not the same -- it's the junction block that connects to the line from the master cylinder.

Pics are below.

Does anyone have two good junction blocks they would be willing to sell? Thanks!

I had a similar problem a few years back. Please take a look at this thread, and what I ended up using:

Brake Hoses/Lines

I was trying to find some photos of what I did, but there's nothing. It seems that I concentrated all the pictures on the differential gear and bearings setup.

I bought the following T-fitting: Earl's#361-972052.

I should clarify that I also changed the flexible hose, and that was the whole reason of changing the T-fitting.

Thanks Esteban. That might be my fall back plan if I can't find some good used original junction blocks. (I did go ahead and order one off of eBay, $16 with free shipping, to see how close they are to the originals in dimensions.)

Since I have all the new brake lines made, and already have the brake hoses, my preference would be to stay with the original junction blocks if at all possible.
