[V8] O-ring help

[dsaad at icehouse.net]

I searched high and low for a compatible o-ring and came up with nothing. I
ended up ordering them from the stealer.
They weren't that expensive - but I had to wait.
I had the same issue with most all o-rings on this car. Even when I know the
size (which is often in ETKA), either I can not find it, or the material is
wrong.
