Prolly gonna take a good share of the day. The key is to make sure you have a BFH to get the firewall pushed back to make room for the pipes. Especially where the firewall and the floor pan meet up.
IIRC EZ used a scissor jack and was able to wedge it up in there to do the trick.
Also that heat shield on the passenger side floor pan is a PITA to deal with as it needs to be pushed up as well. What I know now is that I would have removed it before hand as the clamp for the DP slip joint is right in that area.
I did kinda cheat cause I had the cab off at the time.
I do have some photos in the Golddigger link in my sig that shows the area that had to be pushed back to make room.

Any idea how many miles on the turbo. Mine has a wee bit of radial and axial play but runs great and has over 90k on it.
