The S-10 4x4 is the best trans for the stock A chasis swap with the Torque tube addapter. The S-10 gearing is fine. 1st might be a little low, but with a full syncroed trans you don't realy mind. Starting in second is almost like the stock A 1st. Steve Serr told me last week that it should be soon (he is having the casting paterns made) Once I get some casting, it won't take long to put some kits together. He told me that he would like to have a couple of kits to take with him to the next Turlock swap. .
