For the crush washers the pelican parts guys can get them, just give them a call. They can find you any special order part
For the IP installation don't worry, it's very easy on a stand:
Set the crank to 26*BTDC, on the compression stroke
Set the cam to the timing mark
Set the injection pump splines to their respective timing mark (there are 2 positions-depends on the build date and serial # of your pump)
install the pump.
Then perform the drip tube timing procedure (fairly straightforward, you can make your own tool)
