Kenmore freezer 253.21041103 basket issues

I just recently acquired a used Kenmore 253.21041103 model upright freezer. Problem is that the two slide out baskets that came with it don’t fit the brackets on the side of the freezer. Looks like the basket were made too short.The person that owned it before didn’t use them.
I noticed that this was discussed in the forum about 2 years ago but I didn’t see where there was a fix suggested other than to look at the diagram which I already have and all the slide brackets and baskets are correct. I’m looking for a fix to make the slide baskets functional…
