help with 67 power steering

[2500HD]

I have a 67 SWB with auto (powerglide), cold factory A/C and power brakes. It has a mid 80's model 305 with all of the factory 283 brackets and tins. I am looking to buy a power steering set up from another member but was wondering about possible problems with a 67 model. Some issues I have heard of are -- dimple in frame for the box and different steering column rod. I already have the second pulley (third groove) for the crank. Is there anything else I am missing? Surley someone has added power steering to a non power truck.

Any insight would be helpful.
