Dave,
I bought the new fender extensions from an owner that is on this site. They ran around $220.00, if I remember correctly.
I am curious to hear from others who have bought the same set of fender extensions if they have had any problems with rusting, or any other issues.
As far as the PIAA 520s I got those for around $250.00 for the set including the wiring. Since I already had mounted from the factory/dealership the Bosch Off Road lights on my factory wrap around brush guard I used that wiring harness for my PIAA 520s.
I believe that the lighting pattern on the PIAA 520s is quite different than the lights shown on the site you mentioned. I know PhilD has posted quite extensively about lighting and you may want to check those posts or talk to him as well. Hopefully this was of some help for you.
Respectfully yours,
Gary
