Head's a shed
For those that wanted a few pictures, here you go.
Copied and pasted from my build thread, just re-added pictures as they had disappeared.
So the day of reconing arrived about a month later and so did a bag of goodies.
Basically the gear is made up of the old zf prop flange and the LT230 input gear.
zf prop flange turned down and welded to the input gear.
And the adapter plate, which was laser cut out of 25mm steel plate.
And has a pocket milled out of the back for the zf.
This is what the back of the gearbox looks like before we started and what we had to contend with.
Plate bolts to the gearbox.
Screw the drawbar onto the gearbox output shaft.
And put the new gear on.
So this is effectively what you have but with the gear inside the transfer box usually.
Or if you look at it the other way, put it in the transfer box and the excess pushes onto the gearbox output shaft.
I decided to do a test run with it on the floor as opposed to struggling with it in the vehicle.
So stick the draw bar on the end of the gearbox, new input gear in the transfer box and slot the box on.
Then the original zf prop flange nut put on to hold all the gubbins together.
Both boxes are very close,to get the transfer box as low as possible to improve prop angles.
Needed more so on the 90 as the rear prop ends up quite short.
And that was that sorted, Just to fit now.
