Nothing wrong with having a t-5. If I remember correctly it has a granny low 1st gear.
You can try Novak Industries, or Advance adapters for the correct input gear to match the 2 together.
The only problem that you will probably encounter is needing new drive shafts made because of the different lengths of the drivetrain.
