I believe the quote was $160.00 to rebuild it. This does not include shipping.
Since doing the Vortec swap my truck's steering seems to be suffering from the additional pressure produced by the new GM PS pump. Very wayward on the highway, easily led astray by ruts, etc. Didn't seem an issue before but I believe the gear box is shot.
Got a few other things planned for it that should greatly improve handling. Will post up as it comes together.

You mentioned "wayword" steering on the highway. Check the castor angle on the front end. The V8 is much lighter than the 2f and likely sits towards the rear farther than 2f also.
The rebuilt steering box will be nice, and correct castor will mame steering really nice.
