Even the expensive aluminum master cylinder cap from Motive isn't as good as the GM J tool because it doesn't have a plug in the center with an O-ring that seals the cap to the master cylinder. You can find the J-35589 GM pressure bleeder master cylinder cap on Evilbay all the time. I paid $15 for mine.

Those are great for the GMT800 trucks. But these GMT400 trucks have a big square opening in the top. Its hard to get a pressure bleeder to work on these.
