Last year i bought a set of Matrix racing seats and had them reupholstered to get rid of the Matrix emblem. i didnt have the brackets to install them at the time, but now that i have the brackets i cant find the sliders i had for them. i called Matrix and they told me they dont sell replacement sliders, and ebay only had car specific sliders for toyota etc. and Sparco sliders which i didnt know if they would fit. anyone know where i can get a set of universal racing seat sliders? or if the Sparco ones will work? the seat brackets i got are Weapon R.
