[s-cars] Rear ABS sensor and HRSB links

[tr0910]

I have the Happersized RSB installed and a weak point seems to be the
bracket break that holds the link to the axle.  After it broke, it swung
around and took out the boot and the ABS sensor.

I fixed the bracket and the boot, but now need to get the ABS sensor
replaced for the passenger rear side.  Stealer price is $250, and
GermanAutoParts.com shows it on the site, but admits they can't get it any
longer.  ECS Tuning is the only place I can find it, but price is close to
stealer.

Any other good places to find the ABS sensor?  Part number is 4A0927807C

I probably should also replace the HRSB links while I am at it.  The swivels
on both ends have eaten a lot of dirt and now have some play in them.  (at
least they don't squeak anymore)
