Does anyone have a new, never installed OEM GM return line that you could take some good OD and thickness measurements in metric and imperial values? The Napa replacement kit, like other aftermarket kits, sucks because unlike the oem fittings, the aftermarket fittings don't have the 'wings' over the nipples to protect them, so the nipples are retardedly easy to break while installing, and the o-rings on them seem to be larger than oem as they are really tough to get in. I've found a size or two that seem to 'work', but they were still tough to get seated. I can't imagine the right size isnt out there, but I'm pretty sure I haven't found it yet.
So can anyone help me out?
