I am after some solid info on putting a surf R series box into my LN106. I have searched but there seems to be a lot of mixed info around. Here is what I need to know.
1. Do I need to modify the driveshafts? Will the surf rear one fit?
2. If I adapt the existing gear driven xfer case onto the new box will I still need to modify the driveshaft?
3. Do I need to change the crossmember?
4. How much better is the gear driven tranfer? Is it worth the expense of the adapter to fit?
5. How does the R series compare to G series ratios wise?

Thanks in advance, these answers will save considerable time rolling around in the mud under the parts truck!

The R series box should bolt to the engine and you should be able to use the same clutch (you will need to make sure you have the r series box to L series engine bellhousing)

from taking an r series box out of mine (needed gear driven transfer for duals) it appears that the box is about 10mm shorter. Mine had a spacer on where the rear driveshaft bolts on. I would say that using a surf one piece driveshaft would work instead of the spacer. Standard front driveshaft worked on mine.

You might also need to cut the tunnel a bit bigger as think the gear leaver is slightly further back.

you will need to wire up the push button 4wd

You should be able to use the standard cross member but you will need to get the rubber mount for the r series box.

Thanks for that, very helpful!
