transmissions 1rst gen vs 2nd gen

[shouldi]

i was wondering, has anyone had both the 1rst & 2nd gen. transmissions apart, are the shafts the same, i know its a stretch, but is it possible to put 2nd gen 5th gear, in 1rst gen. , even if it would fit, i know the ratios are wide, but would be a great highway ratio, and i think the engine would pull it, thanks

The cases are the same, but I think you have have to change out the entire shafts, gears and all, not just 2 or 3 gears.
