I need a Sunroof gasket where
 

is the best place to order from?

Which brand, if there is a choice, is the preferred?
TIA

Why do you think you need a gasket?

My problem was clogged drain holes. Pinched the drain nipples near the rear wheel wells and it was fixed.

Think we ran some weedeater line up there to clear it out.

The top of the seal has separated and is sticking up. Probably from freeze thaw and age. Not leaking yet but looks like just a matter of time.
