how do u remove rear 3 sparkplugs

I don't think there is a real answer to that question!... I've got all the tools, even to roll the engine foward...and have been doing this stuff for a very long time, it's still a b---h to replace those 3 plugs!!! ... All I can tell you is good luck!... Also keep in mind it's very easy to crack the new plugs when installing them back there... You might want to just have it done!... Save all that 'skin'....!!!
