Where to buy concave washers/shims on upper control arm???

[wgeyer88]

Hi guys,

While cleaning up the mess I made during disassembly, I somehow managed to throw away all four of the concave washers that go on the control arm mounting studs between the frame and the upper control arms. The washers are flat on one side and concave on the other side. I've checked Napa and O'Reilly in town with no luck. LMC does not seem to have this part either, although it's difficult to tell from their diagram. Does anybody have any idea where I might be able to find these washers?

Thanks in advance for any help!
