I'm looking at going with a 21mm BAT bar for my 2000 SVT. I read one post where a fella had problems with his sway bar mounts cracking on an SVT with the 21mm bar. Anybody else have this problem? Someone also mentioned the possibility of stronger mounting brackets being made. Anyone know of any aftermarket brackets?
