I also did mine last weekend. I was sweating like Patrick Ewingfrom all the stress. I had removed mine a year ago and cleaned them so I had roughly 20k on them. I only had one cause me some concern but it broke free around 33-35 lbs. They had a fair amount of carbon build up, I'll clean them off and keep them in case of an emegency situation.
The Champions were gapped to .045 upon arrival and honestly they run great. I used Nickle Anti-Seize just for piece of mind.
RockAuto had the best price and witha $16 dollar rebate. Thanks mbishop1279 for the heads up.
