Is it a difficult job to get out the flywheel with the engine still in, or is it an engine out job. This sounds like a mod i want to do, but ill never have a reason to take out the engine, unless just for the sake of it and to learn etc. What type of flywheel will i have 020 or 02a? i have an 88 gti 16v, but with a 9a bottem end.?
