[V8] Reference sensor R/R HELP!

[jpb3wvu at frontiernet.net]

Hi,
After searching the AF Archives and looking at the service manual
I still cannot find a write up on how to remove these sensors.  I
know I have read in the past on this forum that there is a
preferred way to do this.  I think someone has mentioned taking
the DS tire off as well as removethe DS distributor.  Can anyone
point me in the right direction here?  I would like to do it this
weekend if possible.  Thanks for any insight.

John
