Where can I find bushed rod ends for 4 link?

I'm building a 68 Hemi Dart for street/strip use and want to put together a 4 link rear suspension. Where can I find the rod ends that have bushings instead of spherical ball ends? I know Speedway sells them, but only for 1/2" bolt size.

Thanks,

Joe

 

I picked some up here http://www.gravity-werx.com/index.asp
also I think suicidedoors.com has em

 

Bushed rod ends are not typically used in four bar setups because of the amount of movement around the pivot points. Bushings are supposed to flex. Not roll or turn.

 

suicide doors.com best prices and shipped fast

 

Agree, suicidedoors.com.
In a Hemi car, I'd use the ones with the 1 1/8" threads!
I make adjustable upper rear trailing arms for very low GM cars with them, using their 1/4"wall 2" tubing, and the dedicated bungs. Very strong!
