Youtube Video on Grenaded Boxster engine
 

Interesting comment about having to pull out the convertible top because they couldn't get it out of the way enough with the aftermarket glass. I wonder if anyone else with a GAHH or other retro glass has run into that.

Even with the OEM glass windowed cars it's a pain to work with the top on when you have an engine removal because the glass makes it much more uncomfortable for the tech to reach some of the connections on the top side of the engine.
A plastic windowed to can just bend out of the way.
Happy Boxstering,
