Double wheel roller replacement for an Alside sliding glass door

I'm looking for replacement double wheel rollers for two Alside sliding glass doors. The dimensions are below and two pictures are included. Any help with this will be appreciated.

Attachment to door is one screw through the top of the housing.

Housing Length 3 1/8 "
Height 1 "
Width 1/16 "

Wheels 1 1/4 "

Thank You,
Jim
