I'm getting excited to get some measurements made
Interesting. Thanks for the pics. I'll have to measure mine as well next time they are off. Get a second point of reference. But to throw a wrench into measuring the old bolts... we don't know their history of torquing. Most mechanics just hit these with an impact, give it a few good uggaduggas, and call it a day.
