Lower and adding PS question

[tsmith8]

I have a '58 Apache with a SBC 327, mostly stock front end with the exception of a disc brake conversion kit.

I am pulling out the 327 this winter to add in a 383. While i am doing this i wouldn't mind lower the front end and adding power steering. I remember reading awhile ago about some things to watch for when it came to lowering and adding power steering on a straight axel but couldn't remember what it was.

Anyone have any input? lowering leafs VS drop axel?

Rack and pinion or power steering box?

steering shaft need to be replaced?

Thank you.
