DIY: Pointers for R/R Knock Sensor ('88 5kCStQW)?

[steveb@falcon.kla-tencor.com (Steven Buchholz)]

I'm going to install a new knock sensor on the wagon tomorrow night.  
I have contemplated the task before, but it seems like there isn't 
sufficient clearance to get an open-end wrench in there and turn it.  
Since the sensor has a reasonable extent I'm assuming that I can't 
get a socket on it to use a ratchet.  I'd appreciate it if one of you 
folks out there that has actually done it could give me some pointers
on how you did it.  Now that I think about it there is a strict torque 
spec for installation ... I guess I've got to figure out some way to 
get a socket on there.  Could the socket that is used for R/R of the 
OXS happen to fit?

TIA!
