...to make some large tracks for... uh, a... um, tractor... Now, for the life of me I can NOT seem to find what cog toothed wheel goes with this wider track. Most of the sets I see have gubbins and stuff in the road so I never get a clear look. Does anyone have these or have knowledge of the parts I need for this si I can make what I need?
Cheers!
