Eddie, I might be able to help you out - PM sent

A D2 transfer case may not work for you. You may need to confirm this, but I thought the D1 has a cable driven speedo with the drive coming from the transfer case. The D2 has an electronic speedo and so LR apparently removed the speedo output from the LT230's which were used in them.

I have a 96 D1 and it has a transducer on the Transfer with just wires, no cable. May be earlier D1 had a cable?

I have a '95 d1 and it too has the transducer...

The D2 transfer case (all years) does not have the speedometer transducer on the rear output housing. On the D2 the "road speed" is calculated by the SLABS ECU. There is a recess in the rear housing where the transducer was mounted on earlier variants but the casting isn't drilled out.

Other significant differences if you are swapping transfer cases between models are the larger front output flange on the D2 and the hi/lo ratio switch on the upper front face of the D2 front output housing.

Additionally 03/04 models have two CDL switches on the front housing whereas earlier D2s (with the CDL internals) have one CDL switch as does the D1.
D2s without the CDL have only the hi/lo ratio switch on the front housing.

Typical L/R, lots of small differences that complicate the use of very similar parts between models.

regards

X2 mine is a 96 update.

Well I just bought a D2 transfer to replace the one in my D1 and it has the casting drilled out, but it is also a D2 with the proper CDL h/l difflock , may be there is the difference?

You may have an ex-D2 transfer case with a D1 rear output housing fitted ? - need to do that to fit the speedo transducer for a D1.

I can't confirm that, but it came out of a D2.
I saw something on the net, don't know where, where it was a vid or pics, but they showed a transfer case and it said they drilled out the casting if the casting was filled
