I had a steady stream of antifreeze dripping from a joint towards the
back of my '84 Vanagon where three rubber hoses come together. It
turns out that the Y making the connection between these hoses had
rusted into oblivion. It was just attached with hose clamps and I
actually managed to get the part out intact but now I can't find a
replacement.

It is a metal part, shaped like a Y, with slightly barbed fittings
off in three directions, the openings appear to be 5/8" to 5/8" to
3/4." Has anyone had to replace this part? Any ideas on the part #?
Anybody got the piece lying around?

Thanks.
