Hello I got your comment.
Sounds like you are going to make quite the project out of your '58 huh. I am going factory stock with mine. For me the speed will not be a problem. I don't even drive my everyday Mits. Galant freeway speeds. I honestly think I am the slowest driver on the road and I am only 23 hahaha
I will probably be driving slower yet once I get my truck back on the road.
Do you mean that there are issues and that is why "it is a bear to drive" and "hard to park". Or do you just want power steering ect. I'm not putting any power options on my truck, I enjoyed driving it for the short period I did some 6 years ago now with no power steering or brakes. At that time my truck was burning almost as much oil as gas. In a 50 mile trip I was down atleast 1 quart of oil LOL
