Control Arm shaft bushings - proper name?

[davepl]

I'm ordering all the parts to rebuild my suspension, so be prepared for a bunch of noob questions from me on it!

For my 3/4 Longhorn 1970:

I'd like to retain my original control arm shafts, but I can't find the rubber ring things that go in with them. I can buy entire replacement arm kits that include them for as low as $5 for the uppers, but the lowers get pricier.

Is there a name for these things? I might not be searching properly... at least on Rock Auto I can't find them.

Thanks!
Dave
