I'd check Chevy Duty. That's where I got most of mine. Also the Filling Station, Carters, etc., stock parts. As far as the old needle, I'm assuming a '58 is about the same as my '53. You just grab hold of the metal piece that holds the needle and gently lift it straight off. It rides on a small sprocket and you put the new one on the same way. Someone else may have better directions as, like I said, theree may be a difference between a '53 and a '58, but I doubt it. I just re-faced my gauges and am very happy with the parts I got from Chevy Duty. Decals are easy to install by using a little windex so you can move them around and place them where you want them before they dry. Hope this helps. Good luck!
