I have suitable replacements.

Early:  http://busdepot.com/details.jsp?partnumber=253067285

Late:  http://busdepot.com/details.jsp?partnumber=255070802B

We list the break as sometime in 1987, which is more accurarte than '85.
There is no doubt that '86 used the early style. Still, like Jim, I have
found the break point to be "iffy."  I have seen late '87 models that took
the early cap, and at least one early '87 that took the late cap. It may be
that Westfalia was using whatever happened to be on the shelf in '87 and
it's not a clean break at all.  The difference is so minor that it's
impossible to tell with the naked eye, making it a coin flip knowing which
to order if you have an '87.  (One option is to order both and return the
'wrong' one.)
