I recently ordered a copper manifold gasket for the L28 in my 240Z via EBay’s GSP (no other option) and paid extra for customs prepaid shipping. It took almost 4 weeks to get the package and DHL held it hostage for the clearance fee and HST, even though I had prepaid them to EBay. The shipment sat in the GSP hub for almost two weeks.
I should have shipped it to NY and imported via CrossBorder.. I think they charge $11 per shipment.
