Well I decided to detune my 03 and get rid of it. . But before I do I decided that I will swap out the 5600 into my 98 and put the nv4500 back in the 03 before I sell it... . I pretty much have the nv5600 in to the 98 figured out, but was wondering how much of a bugger it is going to be to get the nv4500 back into the 03... I know that the driveshafts will have to be shortend/legthened, but what else?? what about the cross member???
