The O-ring on my speedo sending unit is I think stretched a bit and will not allow me to reseat the sending unit because it now sticks out over the lip when trying to reinstall the sending unit. I was wondering if any one knew of a sourrce for a replacement or at least the size specifications for a replacement. I checked the Fiero Store but I didn't see one there. It's for a 86GT manual transmission.


Thanks for any info,

I found a hydraulic repair place not to far from me, and they found a o-ring that worked.Really nice people. I had to trim(sand) it down a little, the tolerance is really tight on that orifice. lol orifice.
All I have to say there is something to be said about small local shops(businesses) .
