It will be just a restored work truck, but needs to drive at highway speeds...65-70 mph | | | | | Joined: Dec 2001 Posts: 1,248 'Bolter | | 'Bolter Joined: Dec 2001 Posts: 1,248 | You can buy a ring and pinion set for 3:55 ratio that you swap in your existing differential and torque tube in place of your 4:10 gears.
John | | | | | Joined: Dec 2001 Posts: 1,248 'Bolter | | 'Bolter Joined: Dec 2001 Posts: 1,248 | The only other way to get to 65 mph would be to swap in something like a modern 5 speed T-5 transmission and open type differential.
