[Discontinued Bushing HELP!]

Do you know where I can find a good schematic of the rear differential? I should have taken some pictures while it was up on the rack

Thanks for the suggestions.  I will check out Super Pro.  Has anyone out there made one?

[Discontinued Bushing HELP!]

I have a 1992 Loyale SW. The bushing at the top of the rear differential has fallen apart.  I looked on line and called Subaru but the bushing has been discontinued.  Does anyone know where I could find one?

Thanks for the help Guys. It ended up being the oxygen sensor.  Now I have another problem.  It snowed and the roads got icy. I took the Loyale out for a spin and she was all over the road.  I got her up on a lift and it looks like the bushing at the top of the rear differential is falling apart. I looked on line and called Subaru. The bushing is not available any more. Does any body know where I could find some vintage parts?

I just bought my first Subaru.  It is a 1992 Loyale with 148K on her.  I want to use her as a daily work vehicle. I can't explain it but I like the way the SW looks.  It had some electrical issues with the head and tail lights but a bad ground repair fixed that.  It runs good but the check engine light comes on when the engine warms up.  Can anyone lead me to a sight that can tell me how to check and read codes?
