In tank pump because it s quiet, no other reasons

if you are going with a rack and pinion, I m afraid you need some more GM parts, I have one from a cavalier that I m going to use on my car, don t know when since it works good with the manual steering but it s in the plans
There is a kit for 55 ford that is very similar, going to copy that one
I cant remember the manufacturer but I bet google can help you

Here is some pics of my tank
