TC soeed sensor seal... standard O-ring?

Got a little leak out the speed sensor of my 231... found this thread

which indicates that I should check the vent but also probably replace the seal... question is is it a standard O-ring which I likely have in my kit, or should I defer working on this until I can get the right part from the dealer? If it is a std. o-ring I will address it today because I already have the heep on jack stands...

thanks!

I would try to match the o-ring as close as you can. If its a major leak and you can't find an o-ring use a little RTV temporarily.

Just an O-ring, nothing fancy, other than its large diameter

cool. I'm on a roll with the bolts - got one shock completely off - so I'm going to keep working on that, but if I get both shocks off and the skid down I'll start on that then.
