1987 Vanagon with TiiCo Conversion

I was wrestling with a leaking power steering hose this morning and
bumped the return line to the reservoir and the reservoir cracked.
I've attempted a repair and haven't tested it yet, but I'm thinking
that if the reservoir is that brittle with age, perhaps, the time has
come to replace it (the reservoir, not my Vanagon).  However, my
search for a direct replacement has not been fruitful.  VanCafe lists
it, but it is not in stock,    Does anyone know of a source?   I've
wondered if a reservoir from another VW model might work.  I noticed
that the Jetta/Golf ones do not have a filter, their hose connections
(barbs?) exit on opposite sides of the reservoir unlike the Vanagon's,
and I have no idea if the hose barbs are the same diameter.  Any
sources, ideas?

Thanks in advance.
