Seems to be a brand X door. Sorry, my son thought it would be fun to take them apart and bend them all up. There are two of them on the door. There are no marking on the part or the door that we can find. Please help!

I'm afraid your roller is no longer available. The closest option we have is the 81-277. Take a look and see if you could use this as a substitute. If not, take a look at the 81-228, 81-266 and 81-310. If your housing is good maybe you can just replace the wheel.
