brake bomb HP hose and fittings.

[Daniel Stevens]

1987 5000 turbo quattro ~90k miles. southern car mainly/mostly rustfree.. 

My brake bomb is leaking. haven't been under the car yet to get a good look. 
but went to the u-pull-it to find a good used and couldn't.  
they were rusty/crusty one was wet and obviously leaking all over. 
which mine may likely be doing also.. 

doesn't look like a fun piece to replace. what part of a 'rebuilt' bomb do I get from some of our list sources? does that include the squareish part the brake hardline connects with? 

FLAPS has the HP hose for $130~  

anyonehave any insights to offer?
or a quality, working non-rusty used one getting thier shelves oily. 
Thanks
