Mike ??? you out there :anyone:don't go by me,mine was 3/8 you would think 5/16 What Wayne says.

Inline Tube says 5/16 for the 84 El but I have seen 3/8 also on other cars.I've only seen 5/16 on early cars like our El's. Good question

They are 5/16 stock. As were ALL RWD GM screw in lines. Roy, that's not very common. The fittings at the end of the lines are a 1/2 hex. To have 3/8 lines you'd have to be running a 9/16 or 5/8 hex. Is that what you have? :beer:
