I agree with the others about staying in close contact with Lugnutz. I did the T5 swap in my 52 3100 5 window. He was a wealth of information and help. Not too sure I would have gotten it right without him. My T5 came from an 88 Sonoma with a mechanical speedo. exactly what I needed. Pulled it apart. everything looked good but rebuilt it anyway. Bolted right up. Love it.
