snap ring HELP !!!!!!

Hi everyone i was working on my 1988 honda fourtrax 300fw sprung a leak at the transfer case now i pulled the cover off for the shaft that runs from the transfer case to the rear diff and noticed that the backing washer and the snap ring were mangled on the shaft my question is how do i get that shaft out to do the snap ring and i would imagine that the backing washer wopuld need to be there for spacing on the snap ring not sure thanks in advance
