Don't buy Fleece lines

Ordered a set of lines for my 2006 Duramax, LBZ. Fleece sent the wrong fittings for my transmission cooling radiator. Called Fleece up to get the right fittings. Instead of sending the right fittings, they suggested using 2 O rings. Why would I do something stupid like that? Great lines, horrible tech support. Will never recommend Fleece. If you are reading this, I suggest you take the old lines to a hydraulic line shop. They will make lines just as nice, put the right fittings on and charge you less. Fleece, you suck!
