Best resource for parts? 4 Suburban Ventshades, roof rack

[timmyraines]

I've scoured the classifieds here and googled several times and cannot find anything but old classified threads selling all four ventshades for suburbans or crew cabs. Also would like a roof rack that is close to period correct but nothing out there but people who make fancy wooden ones. Just want the classic wagon stainless steel roof rack. Not picky on either item, NOS, used or reproduction replacement part. Any websites or advice welcome.
