Would be any other issues other than the 25det and 20det output shafts being different. Will I run into length issues or anything with the tailshaft

Ecu had no problems running a 25det box in the months before hand.

It's not an ecu problem

My 25det auto trans decided to spit the dummy As being a frequently used vehicle, and shipping on my manual conversion taking it's time. Thought I'd slap in a 20det box in the meantime as theres one sitting in the back of a mates shed. But after pulling the 25 box out I found that the output shafts are different, and my mate doesnt have the driveshaft with the 20det box. Before looking for a 20det driveshaft, was wondering If there would be any other issues other than the 25det and 20det output shafts being different. Will I run into length issues or anything. Or should it bolt straight up.
