My mid-80's load rite trailer is in desperate need of new rollers. It currently has regular black wobble rollers held on by a pin driven through the shaft. Can these wobbles be safely replaced by something like the ribbed poly rollers made by Tie-Down? They come in nice convenient 4 packs and won't leave these blasted black streaks on my hull. While I'm at it, can I retrofit hog rings for the old rusted roller pins?
