Subject: Installing Golf/Jetta/Fox Speedo in a Syncro w/ Oil Pressure Buzzer
To: BenT Syncro <syncro@gmail.com>

Hello All,

It is well known that the MPH speedometer for the Syncro is NLA from VW. In
response to a fellow Syncronaut Craig's unsuccessful attempt to locate a
replacement speedometer for the one missing from his recently purchased
Syncro, I decided to assemble one from a Golf/Jetta/Fox based on information
written previously by fellow listmembers. I specifically read postings by
Mark Drillock and made phone call inquiries to Dan Fleming.

For my project, I decided to use a speedo from a late-80's to early 90's VW
Fox because it is a close match to the Syncro 1600 speedo at 1575 (plus I
found one with very low miles with very little wear). Since VW tended to
calibrate their speedo's to read faster, this arrangement may actually yield
better accuracy. I have the speedo assembled now and pics with captions
posted here:

I have not figured out a way to add the dynamic oil pressure printed circuit
yet. In the stock plastic Vanagon backing plate there is small recess for
the buzzer and a hole for the harness connector. None in the steel
backingplate. There are PC board is held in place by molded clips in the
plastic cluster. Those are absent from the steel backing plate. I am looking
for suggestions to this problem before starting to cut holes in the backing
plate.

(NOTE to my friends on the OZ List: I am sending a copy of this email to the
group in case you run into the same speedo shortage we are having in the US)

Corrections and comments welcome.
