im looking to do a 12 valve cummins swap into the truck in my sig, i found a 6 speed from a 2001 8.0L v-10 dodge. i believe a nv4500 from a cummins and a v-10 are the same tranny, my question is if the nv5600 is the same way, and if a nv4500 bellhousing to block adapter is the same as the nv5600, as the adapter would not be available from the v-10. thanks for any and all help.
