From what I have heard you can take a turbo-350 tranny and cut 1.5 inch's off the output shaft so that it will mount up to a 203 t-case, I'm assuming with a 6 inch output shaft, (or maybe that's what it need's and it comes with a 7.5 inch), I've searched all over the net, I've seen it done before but just need to know the right output shaft lenght, Have a wonderfull day, and thanks in advance if you know
