Wheel assembly for porch slider

Hello. The wheel is steel 1 1/4 " diameter..3/8 " width. Markings on the case are "ALLEN STEVENS CORP." "WOODSIDE,NY" "6049" . Wheel assembly is stamped "6047"

Additional information: body width is 3/4'; body height is 1 3/16" body length is 1 3/8".

Overall measurements including wheel is 1 3/4 " length x 1 3/16 " x 3/4 " width (width including tabs is 1").

May I also have information about kits to replace the wheel? Thank you.
