What size is the idler arm bolt?

[bull]

Near as I can tell it's a 9/16" NF bolt that's 3 1/2" long with a castle nut. Is anyone selling them because I can't seem to find this size in the 3.5" length.

This is for the steering idler on a 68 BTW.

The idler to the K-Frame? I think Frank Badalson is selling the correct style - don't know if anyone is selling a generic one without the idler arm.

Thanks. I've never heard of that place but it looks like they've got a lot of good stuff.
