Couldn't download my pics to your forum. Here are three pictures.

Length is 1"
width is 3/4"
height is 1/2"

There are two channels on the bottom of the plastic guide. the width is 3/8" wide

the cradle for the wheel is 3/8" wide and 1/4" from axle to plastic base

Can you recommend a replacement?
