After having recently done this job twice, I don't see where it would be all that beneficial to modify as it is so easy to fix.

The first time, I did it the hard way and tore up the grommet and had the wrong size o-rings. Some hints..........after unbolting from the turbo end, push down firmly on both pieces and with very slight prying pressure the top will come out easily. Then separate the two sections and wrap, in a spiral, some strapping, around the bottom tube and secure with a couple of worm gear clamps, top and bottom. Put a loop in the other end of the strap at sufficient height that you can insert a pry bar and lift. It'll pop right out. Make sure to clean all surfaces and polish any burrs, etc. that might cause problems. Then install the new grommet using KY and slide it up the bottom tube a bit. Install the o-rings, insert the bottom tube then insert the top tube. Then put it back in position to bolt at the turbo before you place the new gasket. Bolt in place and the last item is to lube, again with more KY, then push the grommet down and seat it. (KY works great as it is so easy to clean to no trace afterwards. This helps to make a good seal.)

I have seen several posts on this task and many have parts that make this more difficult than it should be. With these tips, I can now change o-rings and grommet in short order, without all the frustration.
