Ventmaster, thanks for the advice! Yes, you really can't mix them up, front-to-back (or I should say "you shouldn't"), as the connectors are different.

Great tip on putting the boot in the flange before screwing in the sensor!

I have the sensor socket. And I have a really long single piece Snap-on extension. But I am debating whether to put this car on jack stands, and do it myself, or "farm it out". I was asking some guys on the forum who are from my area about a previously mentioned local exhaust shop. All of my favorite shops from the past are gone....
