I believe they all do(MK4 3-door(only) Sunroof). a site called BCS-tuning seems to cary a lot of OEM parts , they might have what you are looking for if you haven't found it yet.Been trying to get some interior grab handle mounting brackets from the US as there obsolete here in the UK.
They dont even cost that much to buy but i just can't find any.
From a mk4 r32 3 door with a sunroof. I think all r32's in the US came with a sunroof?
Any help would be appreciated PM me.
