what gasket?

hey guys,

my pan is leaking, its a new pan. TF904

1974 PLYMOUTH DUSTER 5.2L 318cid V8 Filter | RockAuto

the funny thing is im from the netherlands, and a guy a town over has an American transmission shop.. he asks 31 dollars for a simple looking cork gasket and a basic filter.

on Rockauto i get more choice in material/quality + its half the cost of what he is asking.. all the way from the USA..

but anyway, wich one should i take? the price is pretty much all the same, and so are the looks of the product.
