Product review (5 stars): the replacement of the belt was made easy with some clothes pins
Had lots of marks on clothes after going through the dryer. I knew the dryer need some repairs. I purchased this seal and the Dryer Kit in the link below.

The instructions that came with it are very vague.  Make sure when  you take off the old one to use some sand paper (I used 80 grit) to get the residue of the old glue off.
If I had to do this type of repair again, I would use the following item and i'm certain it would speed up the process:

Never the less, the replacement of the belt was made easy with some clothes pins.  Make sure you wear some gloves as the glue that comes with the seal is very sticky and dark amber.
Comes packaged as attached pictures show.
