There are 2 options that you have. 1st is a shroud from an FJ60 and an 8 blade plastic fan. I got mine from
@65swb45 (Mark's Offroad). Mark is a great person and vendor. The second is keep your stock shroud and get a plastic 6 blade fan. Mark could also get you one--they are still available from Toyota as well. Of the two option, I prefer the latter. The 8 blade fan was too loud for my liking. You will need a spacer with longer bolts that goes between the plastic fan and the water pump pulley. Mark can also hook you up with one of those (I am pretty sure he sells it as a kit). Replacing the 4 blade metal fan is one of the best upgrades you can make.
Good luck, enjoy the journey. Be more stubborn than any obstacle that comes your way and trust me, obstacles and frustrations will come. I and others will be happy to help. There are many, many people smarter than me on this forum that can guide you--I'll fill in as best I can where I can.
