Door from 1972, Del Mar stamp on roller steel wheel, no part number but pat# 3.670.357. Would like to replace with steel or Stainless Steel not nylon. Which roller is correct? Wheels diameter measuring 1 1/4". Roller connects to door via a single top screw.

Hello, Laurie! Your roller looks a lot like our 81-030. I recommend reviewing our specs for this part to start out. Let me know if they differ in any way and I can try to find you something better; otherwise, I think this is your best bet.
