So I bought a replacement steering rack and everything fits together except for one flare nut at the end of a hardline. So I can't replace the flare nut and the hole on the new rack is threaded two sizes too small. Does any online store sell flare nut adapters meant to hold and transfer the power steering fluid? The hardline/flare nut installed in the car is 20mm and the threaded hole on the new rack is threaded for 18mm. I drive a 2008 Honda crv, FWD if that helps at all. Thank you in advance.
