Case 580B Intermediate Hydraulics help

I am buying a 580 B so I will probably be spending quite a bit of time on here.

I am replacing a high-pressure hose underneath the control stick for the backhoe. In my service manual it is part of the intermediate controls.
I am having a hard time finding it online as far as the specs go. But obviously I can just go down to the hydraulic shop and get a piece of hose. My main question is, are these two lines that the hose connect supposed to be in line? Just wondering if anybody could take a peek out their 580 B and see if they lineup.
Because mine don’t line up and the hose would need to have a bend in it.
Thank youIMG_0983.jpeg

Being that it has a hose clamp on it, it is not a high pressure line.
A high pressure line will have a fitting crimped on the end.

As it is a low pressure return line, the hose would seal better with an appropriate size t-bolt clamp instead of a gear clamp. Or, you could double up on the gear clamps. Quite often, a single gear clamp will leak or ooze especially as the hose ages

Thanks everyone.
Does anyone know if the bucket on a CK will interchange with a B?
I can get this CK running but not moving for $2000. The rear rubber and that clam bucket would be worth 2K to me, not to mention a running motor assuming its a 188 like mine.

Mine is the B on the trailer.

They should interchange you'll have to shim in between the boom and the bucket to take up slack.

I’m not sure about loader buckets you’ll need to do some measuring but I think the ck buckets are narrower

I would find exactly what I would have to cut and weld, to make it not worth my time and money.
I have 2500 bucks sitting in a safe for the opportunity, when a 4n1 comes around for my Case 580 SE.
I already have a valve plumbed for a snow plow and can use it for the 4n1.
Im looking hard at the one you posted but I’m reasonably sure it’s too narrow.
That one of my serious wants.
