How would you build a low 10’s street car

How did you mate up to the gear vendors OD to the commando box? I thought they are not compatible with the ball and trunnion design
I called up Passon Performance, and got me an E-body mainshaft. The GVod came with a long-tail adapter so the M/S was all that was needed. And I used a Passon aluminum HD case with his al. side-cover, and my front retainer. The used-gearset, I bought separately, also from Passon, and used my own sliders and brass. Thanks goes out to Jamie for the in-excellent-condition used parts, which I promptly street slick-shifted second and third gears, sorry Jamie,lol..
