I recently did the power steering upgrade on my '66, C-10 utilizing the CPP setup. I didn't use the adapter kit, instead I cut out the necessary length of the stock steering shaft, beveled both ends clamped it in an aluminum "V" block, to ensure proper alignment and rewelded the two pieces back together. I then sanded, primed and painted the shaft, as well as the adjacent frame rail, brackets etc. By doing so, the entire upgrade looks factory original. The sleeve provided with the kit, when installed, looks aftermarket.
I took the auto steering column out of my '66, K-10 that came from a '66 Impala installed by the previous owner. I am replacing it with a factory orginal automatic steering column and shift assembly from a '66, C-10. I wanted to get it as close to orginal as possible and the Impala column, shift indicator and steering wheel look out of place in the K-10.
