Robbie,

Just change the bolts on the 3 legged output shaft to suit the donut you will be using.

The boxes are the same, no need to change anything.

Dave when you sit them side by side escort rear casing is shorter

New to me lol.

There's enough in the prop to compensate the difference, I have never had any problems.

the difference is the middle output shaft

the esocs is longer than the sierra hence the escos uses a thin doughnut and sierra uses a thicker one

the 3 bolts into the 3 legged output are different escos use shorter sierra longer

so to get a escos rear onto a sierrra you swap the complete transfer case over and vice versa

Yeah mines got a Saph gearbox in, just stuck my doughnut on because it didn't come with one and it's spot on.

I didn't need to swap transfer cases or anything, I didn't even realise they were different

some very very late safs used escos gearbox so you may have been ok

thread here to show differences between the rear ends

IMO you will get away with it as where the two props slide together, it will just slide in a bit more.
