90 oxygen sensor

[LEMONHEAD <br00206@binghamton.edu>]

Hi all...

Tried R&Ring the O2 sensor in my 1988 90 today and ran into a couple problems.

First, I went out and sprung for a 22 mm box spanner only to find that there
isn't enought room to maneuver the damn thing around down there!  So off to
Western Auto I go to buy an O2 socket.  I get back, get underneath my car
and now find that there's some sort of friggin' heat shield above the cat
which hinders the socket from even fitting over the O2 sensor.  

How do you get the damn thing off??  Do I have to remove the heat shield, or
is there an easier way?  Is the O2 socket I bought too long?

Second, how do you get the 2 pin connector, connected to the O2 sensor
itself, out of the support bracket which is mounted to the head?  What's the
trick to it??  I'm assuming you don't have to break it off...
