MT2013

My GLS didn't come with running boards. I've found some on eBay that say x166 but when I hit my model it says will not fit. I would assume running boards that fit the 2013-2016 GL would fit the GLS but not hearing any reply from the sellers. Any of y'all know? Getting my multi spoke 22s put on this weekend and thought running boards would complete the look.

Thanks!

It will fit without doubt. Many websites are not updated to take into account the GLS. I purchased my Weathertech mat from Internet, and same thing, it was not showing the GLS as suitable model. I ordered the GL ones (X166) and it fits perfectly.

If you find out they fit, I have a set i removed off a 2015 ML350 (x166). I live in just out side St louis

ML/GLEs are m166 not x166 and I doubt those would fit.
