dont fit well

Dorman gaskets don't fit OEM or new return lines well. The bridge piece connecting the gasket rings is too small so the gaskets don't sit flat on their surfaces and too thick to fit into the ribs on the side of the return line. i ended up breaking the connecting tab so the gaskets were independent when installing. 2003 LB7
