I need to replace the little rubber tip on my sun visors. I believe they are called "Sleeve (Visor Anchor Pin)" I think the part number is: D1DZ-6204115-A

I don't know if the parts stores carry them or if there is something to replace them with but I did find them online at Dennis Carpenter but they do not show them fitting a 1988 E150

the pin itself that inserts into the visor has a groove in the end like this one:
