Has anyone tried the new rockford u-joints? I bought some about a year and a half ago and broke one in 45 minutes. they're supposed to have new ones out again for the third time but I can ever get them to e-mail me back with info. I've been sitting on it ever since cause I can't find any. I do have a line on some napa ones that are supposed to work but i rather get something that was intended for the job if I can.
