I have double-checked and it seems that the pannier frame will fit models GS 2004 - 2012, so there shouldn't be any modifications that you would need to do. Sure not a problem they are still available.
Selling my 45 Litre “Alu Standard” Side Panniers (Aluminium) and rack. Only done about 4 rides with them. Panniers and rack in excellent condition.
Will fit GS models 2008-2012.
Selling as a set.
