Rick,
You've been "bustin' my chops"? I didn't know that. I thought it was just friendly input.
NO!! I am not one of those people that think the proper way to break in a car is the way you're gonna drive it although that is what I am doing since I don't intend on racing it regularly. I am planning on adding the brace to the rear end. I actually have found only one crack and it was not due to too much power, it is in the rear of the center section where a cover would be on a GM rear. This was caused seemingly by someone getting carried away with cleaning up the factory (from Ford) welds to make it look cleaner. What I thought was a crack in the tube was actually my axle vent leaking. I found this when I put it on a lift and got better access to the underside.
I appreciate the concern you have, the last thing I want to do is take my Wife's retirement fund away from her (a.k.a. killing the snake), although she'd be a lot wealthier as a Widow.
Thank you.
John
