Interchange transfer case in

Question: Can I put a NP263xhd in place of a NP261HD vehicle is2001 2500hd 6.0 NV4500 5 speed

Answer: Yes this could be done but the NV263 is electric shift so without adding the switch, module, shift motor ext there would be no way to shift the transfer case.  May be able to track these parts in local salvage yard or on line. Let us now if you need internal parts.You can see detailed drawings and part list on our site at www.midwestrans.com
