Gotcha beat, my tools would never fit in my Vanagon!  Granddaughter might want it anyway now that her father has one. ;-)  However, my daughter learned to drive in my '78 tin top stick shift, and promptly totaled it three months after getting her license at age 16.

My 02 sensor was oval.  It could be turned a fraction of a turn, but no more.

ha. Yes, my plan is to be buried with them.... in my Vanagon!   ;)

My last attempt at O2 removal was futile. But then it was a rusty rusty affair.

Lest I jinx myself before removal of final fasteners at arm to body, would like to say a big "thanks" to list for help on this (one arm is done).

Given all the comments I've read online re: rusted fasteners and what not, would never have tackled this job w/o some help and encouragement.
I'll post tips and things I learned on my picasaweb album.
From the POV of a pseudo advanced shade tree, this job is certainly doable. i.e. arm thickness is quite forgiving for MIG, a propane torch sufficed to heat up old bushings for removal.
And thank goodness for guys like Loogy (Chris) at T3 and the GoWesty perch.

Neil.
