The only place I could order the MSD wires was at Autozone. Got a dummy at the first AZ that was clueless, and couldn't order them. Went to Advance, NAPA and Car Quest, and all they had were el-cheapo wires (yet, too pricey for what they were). Second AZ had someone who had no problem ordering a set. Should have gone there first!
AZ didn't carry the Champion Double Platinum #7570 plugs, but I was able to order them at Advance. Sheesh, these places don't stock much of anything.
Thanks for the suggestions everyone.
