My rear sunroof seal popped out and came apart while I was washing the top earlier. The little white rubber inner piece now won't stay in.
Pelican lists two parts...
Porsche 911 Sunroof Parts - Page 1
Coupe 'Velvet' Sunroof Seal, rear, 911 (1974-98), 911 Turbo (1976-98)
911-564-193-00-M136
and
Coupe Flat Sunroof Seal on roof, 911 (1974-98), 911 Turbo (1976-98)
901-564-905-05-M100
Do I need both, or just the velvet seal?
