P/S Sector Shaft Replacement - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey all could really use you help. I am converting to PS but the steering box i bought had a leak around the pitman arm. I figured an easy seal replacement but when I disassembled the sector shaft/ pitman arm shaft has big groves in it so will need to be replaced. The problem is I can't seem to find a replacement. Can someone guide me in the right direction?

Much appreciated.

Wrecking yard or go to the parts store and get a rebuilt and use your box as a core
