4.10 gears would work nice behind a T5. An S10 T5 is too light duty for a one ton in my opinion though.

Have you compared the width of the new rear to the old one?
(axle flange to axle flange) That '91 axle may be as much as 5" wider than your stock axle width and can give you tire/fender clearance problems depending on what you use.
