[Spyderssss]

I just finished rebuilding the front end on my '63 1500 3/4 ton daily driver, new ball joints, control arm bushings, tie rod ends, pittman & idler arms, ect. ect.
Now i'm trying to get the stock linkage assist power steering up and working again, new power cylinder and pump, all new high pressure lines, only to find that the hydraulic control valve is shot.
Has anyone found a new or refurbished HCV available anywhere? I have found several for the early Corvettes and Impalas, the pictures I have seen look identical to the GMC but I cannot find any info about if they are the same part or will cross over.
Any info would be appreciated, Thanks
