I'll chime in a with a bit more info later, but when I re-did the brakes on the 70 454 Laurentian I had problems getting the correct rear flex hose. The newer ones have a 6 pointed end on them, but the hole in the crossmember is rounded with a flat top and bottom. Plus if I recall there was an issue with the distance to the clip. I ended up getting a flex hose from Classic Industries in California, part # for 70 was FH51, which is correct for both 69 & 70. If I recall, 67 & 68 had a different junction block than 69 & 70.

I had a photo of a Wagner BH73244 hose which was correct for mine, but when I went to the Federal-Mogul website www.fme-cat.com/application.aspx to look one up for a 67 Impala, it showed the hex head for the end going through the crossmember. Is the hole in your chassis like mine that is round with a flat top & bottom?
If you have the rounded sides with flat top & bottom, the fitting you need is made by BrakeQuip, their part # HFIF35. Any hose provider will carry these, and make you up a hose with that on one end and whatever you need on the other end. I found the box that had the original 70 454 Laurentian hose in it, as well as the NAPA hose that was intended to replace it, but didn't work. On the box I had a sticky note with BrakeQuip HFIF35. I actually tried to get a local hose supplier just to change the one end on the hose, but they wouldn't. They'd make me a new hose, but wouldn't modify someone else's hose. This was at GreenLine Hose here in Calgary, but I'm sure you should be able to find a hose provider where you are.
Here's a link to the BrakeQuip catalog, HFIF35 is on page 27:
Let me know how you make out. But doing a bit more digging on places like RockAuto, they all show your brake hose having a hex head going through the chassis, whereas mine is rounded with flat top & bottom. However, those may be "replacement" ones. Does yours have the rounded sides and flat top & bottom?
I've had a few minutes to dig through my stuff and take some photo's.
The first photo shows 4 brake hoses. From the left are: NAPA hose that had the hex head, so couldn't use. Next is the original 70 454 Laurentian hose, next is the Raybestos hose, and finally a hose I likely got on ebay, it's part # HSP4512, but not sure who made it (it's not from Classic Industries). Notice the groove for the clip on the hose ends is in a slightly different than the original.
The second photo is of the end I've been talking about, rounded sides with flat top and bottom. Is that what your chassis has?
I had the chassis from the 70 Impala I parted out last year sitting in my alley, and finally took it to the metal recycler last weekend. I should have verified the Raybestos hose would have worked, as I'm planning on using it on my 70 2+2 convertible here in a few weeks when I re-do the steering, suspension & brakes.

I am pretty sure that I that one precisely. (HFIF35)
The replacement they order are all similar but the connection end is too short for the thick frame.
I'm going to have the shop install the improper part just to get the car home
I will contact our local hose experts, Deetag, to see if I can get this hose made.
Let us know how you make out with Deetag. As mentioned, I've got a couple hoses, but not 1000% sure they're going to work. I know the one I got from Classic Industries (part # FH51) worked on the 70 454 Laurentian, but I really don't remember where I got the one that I put in my 70 Parisienne. I'm fearing I may need to get one made for my 70 2+2 convertible, but I'm pretty sure I should be ok even if that's the case.
That's super. 69/70 hoses have a built in T on the hose, I think originally 67/68 had a brass junction block, but as long as what you get works. For laughs today I called Green Line here in Calgary, I'm going to swing by there tomorrow just to check out the HFIF35 end again. They don't have any, and said it's been replaced by HFIF09, which has the hex head which won't work. I'm just trying to prepare myself in the event the 2 I have don't work and need to get one made.
I put a bit more thought into this, and remembered in addition to the hose I bought from Classic Industries (part # FH51), I also had one made at Green Line Hose here in Calgary, so I dug up my receipt. Yup, it shows HFIF35 on one end, and junction block HFIF25 on the other of a 1 foot brake hose. I stopped there today, and they don't have either end in stock, but can get them. I used the one from Green Line on the 70 454 Laurentian, and the Classic Industries one on the Parisienne.
The line looks great Randy, but I have one concern - The ends don't seem to align. The hose can't be easily twisted, and I'm concerned that once one end is in place (whether it be the chassis end or the diff end), the other end won't properly align to be fixed in place. It's almost like one end needs to be turned 90 degrees.
