Replaceing dryer belt

My Dryer belt is broken and I need to put on the new one. Which panel do I remove from this Gibson Dryer to do so and how is that done? I’m guessing the year of the machine…but the belt that was on this machine was a smooth belt and I’ve ordered a smooth replacement one. The order taker I spoke to said to use the Frigidaire Dryer Belt Diagram but this diagram shows a ribbed belt?

Lift up the top panel from the front and remove the front panel. For the proper belt installation you can use the Westinghouse belt diagram.
