I have 15x8" Draglites on the back of my notch with a 5.5BS. Im gonna get some 275/60/15 MT ET Drag RAdials and its gonna be freakin tight! I just wanted to know if anyone sells those slide on spacers, the bolt pattern on a stang is a 4x41/4 right? I need something in the 1/4"-3/8" range. Lemme know if these are available anywhere, thanks!
