There were some T-5 models with a 3.50 first. If you could swap out for a .76 fifth and if you had a 3.55 gear set in the rear, that would be about perfect if you wanted to run it as a real truck and still cruise on the highway at around 2200 rpm at 65 mph. Your overall first gear ratio would be around 12.5. Mine is 12.37. Sounding better all the time, Jerry.
