Retrofit a 68 C50 with power steering

[abilityonline]

Hey guys.

Any of you ever retrofit your steering column with power assist steering? I've got a 68 chevy c50 and I swapped out the king pins, regreased all the fittings and it's a little more difficult to steer with the old play taken out of the steering. I'd like to hit a junk yard and find a power steering assembly that would work well with this truck. It doesn't have to be 'vintage'. I've already got modern truck parts all over this truck like radiator, seats, etc.

Thanks
