What size is this track..Here is the track number..

[hereismylife]

I got my track off and I am ring to figure out what lug size I got. Also I am tring to figure out what size woodies are in my track. The studs have no number on them. I am new at the stud thing but I am going to search on how to measure them so I know what I am dealing with.

Anyhow anyone know what this part number means?

8EA - 47110 - 10

thanks joe
