[Vwdiesel] 1982 Rabbit with 1.6, which head gasket

[Gary Shea]

Hi Michael!

I like the ruler idea.  You take your 1mm ruler and hold it next to the
piston... oh no I dropped it!  ;)

First, I expect that Gary Bangs is right about which gasket it is, and
this is just a safety check.  I included the gasket thickness in hopes
that you could measure the old gasket if you have a caliper.  It would
be great if it came out right on top of one of the two numbers.
