<< If you have an '81-82 Vanagon Diesel, this is great news.

As you may know (or will inevitably discover sooner or later) , the coolant
expansion tank used in your Vanagon (068 121 405B) was discontinued by VW
over a year ago.  This is a common failure item, and retrofitting a later
style tank to fit involves replacing a bunch of hoses etc., at a rather high
cost - leaving a lot of people hoping that their existing tank will hold
together just a little longer with epoxy and duct tape.>>

There must be a bumper crop of these early diesel expansion tanks. I bought
two of them from two different Ebay vendors for $5.50 & $7.50 respectively.
Of course those are auction prices. With shipping I got them for less than
$20 each.
