    No, they are a different pattern - totally diffferent. The only practical way to mate a T-15 and a D300 is by finding the scarce and expensive manual transmission Scout D300 with a "Texas" pattern.

    Yep. You can swap in some different gears from a Dana 18 and a early Bronco Dana 20 and end up with 2.46 to 1 for about 3 bills. For 6 bills, or so, you can buy a TeraLow kit and go to 3.15 to 1.

    I've got the tera-low in mine. Excellent upgrade. total cost with installation was about $800 with my local club discount.
