Product review (3 stars): Supco 653260 Universal Door Gasket 32x55
I found these difficult to put on.  It came with no instructions.  I did manage to get the gasket on the freezer, but I have to strap the freezer shut to get it to stay closed.  To be fair, my freezer is so old that I was not able to find anything that would fit by the part, serial or model #.  I'm grateful that this gasket works, albeit it's a bit of a pain.
