The T5 was one of the best decisions that I made for this thing. I love it. The S10 version put the shifter in the exact perfect location with the bench seat. (I helped it a bit with the Hurst extension and short throw conversion) I'm glad the rear end was rebuild-able with the 3.90 gear ratio. That seems like the best setup for this truck with the 350 small block up front. I haven't had it much above 60 mph yet, but next summer I'm planning on driving it a lot.
