I don't know where you are in Texas, but In my NTBC FB group people go to Bridgeport and Barnwell. I have not personally been to either but people seem to frequent these two places.

Can you post the website where you purchased your grab handles? Also what color is this blue? I have Black Diamond and trying to match the blue accents! Thanks
