Clothes get snagged by dryer

I have an apartment-sized front load stacking dryer and clothes frequently get caught between the drum and body above the door opening. They get pinched into a notch and get twisted and damaged. Can somebody tell me what parts I need and where to get the right parts? I have seen some videos about how to disassemble and replace dryer parts but my stacker dryer is a bit different layout, with controls on front face of the body. Not sure how different the process is because of this. Any help appreciated!
