| it was easy for me but then again i'm a small filipino... removing the plug from the exhaust manifold was the most difficult part and required a short stubby wrench.  i forget what size i had to get: 21mm or 22mm.  if you can remove the brake master cylinder, that would help 10x.  also, PB blaster is your friend.  the EGR plug that replaces it is some standard size bolt.  i had to buy a short stubby wrench for that also. my motor was only 3-4 years old when i did this and there was anti-sieze on the plug, so i just had to push real hard on the short wrench to get it to go.
