worm bearing part #

Is this the right bearing for our steering boxes? Part #of C2AZ-3571-A
The partial part number listed in an old dennis carpenter catalog is 3571. Im in need of 1a for my steering box and would like to make sure its the right part before i order it.

anyone?

yes, that's the right bearing. the box uses two of them on each side of the steering shaft.
i think the bearing is of a standard size. i once read on FTE to which number this crosses over. might be able to get i cheaper elsewhere!
