These reinforcements are an important part of the body on convertible versions of the beetle. As the roof is missing on the convertible there is no reinforcement and this is replaced through additional plates near to the heater channels and a reinforcement channel underneath the heater channels. Item 0886-100/101 can be found at the rear of the drivers opening at the inside of the heaterchannel/B-pillar. Item 0886-110/111 is located at the front inside of the heater channel. It starts from the front protecting board and continues over the connection with the A-pillar just passing the heater outlet.
