k,there is a dana35 standard and reverse rotation front ends(ford)The TTB 35 is a reverse rotation while the IFS 35 is a standard.i know the gears are different.So,ready,does the t-case(front output)turn a different direction between the two different rotations

so it must depend on which side the pinion is to the ring gear

I have changed from low input to hi input (reverse cut gears) in a Dana 44 axle. The transfer rotation did not need to change. If I remember correctly the pinion stays on the same side of ring gear and rotates the same direction (but now needs reverse cut gears).

Not sure about Dana 35 axles, best to look at both on the ground.
