Help: what is "Strut & Spindle" - (hard parts that don't wear out)?

[EngineerBill]

I bought 1993 Mercedes 190e 2.6L 6 cylinder from junk yard, replaced radiator, cam shaft, head gasket, valve job - car runs okay now. I took the car in to tire shop for alignment and he told me the left front was wrecked, needs a new strut & spindle.

So, I go online and find a strut but can't find what a spindle is. I call him back and told him I found a KYB Gr-2 Gas Strut and he says that's not what you need. You need the strut and spindle from a wrecking yard - hard parts that don't wear out.

Does anyone know what I need? He says the old ones are bent and that's why the front left wheel angles in from the ground up.

I am at a loss and haven't been able to figure this out in forum search or google.
