OK Brent, then the ST will be what I go with. I am online looking for the dimensions and I found this at

I am concerned about the width (thickness). Mine is about 1' thick. I am reading this one is at least 1.578" art its smallest point and 1.780" at its largest. Is this possible? Won't the extra thickness affect my fan belt alignment and crank bolt length needs?
