Yes, they're the bigger of the two, the 231mm. Red wouldn't have been my first color choice, but I haven't run into anything, so reliability has been as good as can be expected. I've even submerged them in muddy water/river crossings multiple times with nary a complaint from them. As has been stated, they're all pretty much the same regardless of the source.
So you recommend these ? Vs Napa or other brand ? Because I was thinking of getting used OEM and rebuild it. And powder coat it.
