I am also planning on installing an S10 T5 behind a 235 in my 51 pickup, I have a rebuilt T5 with a Jeep input shaft, so I won’t need an adapter. My question is, if I change out the center section with a 55-62 center section on my stock rear end, are there new ring and pion gears available in different ratios for that center section? I think I would like to use something around 3.70
