[V8] O-ring help

[Ingo Rautenberg]

Thanks, Dave.  I was able to pick up a few from my favorite local  
dealer (they have them in stock because they're not unique to our  
V8's) and affordable @ $1.61 ea.   Hmm.  That's the least I've spent  
there in quite some time :-)

My preliminary measurements (no micrometer used):  OD 28mm ID 20mm  
and 4mm  thick.
