Ok the 4Vs are pain in the ass but i still wouldnt pay someone to do it. 2Vs are alot easier just because there is so much more room. You will need plenty of long 38 extensions and a universal. It take a large open end wrench for the EGR...1-116or 1-18 dont remember.
As far as O2 extensions Just get some wire and heat shrink tubing and extend the wires on the O2s yourself.
I dont think Ill be free to work on it all night but I might be able to swing by and see how things are going. Keep us posted.
