Thanks for the apologies.

I apologize also as to offending anyone with my comments, I have a tendency to forget humanity when I am engrossed in an issue.

The 12 bolt does not suit my needs as time consumption when changing gear ratios is too high. With the 9", it only takes me 20 minutes.

My goals are directed at engine data, not drivability, and I do not like to waste money. This is why I am reluctant to purchase high end components. I did, however, receive strange components with gear ratios ranging from 3.08 to 5.60.

I hope this ends the issue.
