I had a set of 9.5" wide 17" wheels on the Sy for a year and decided to go with an 11" wide in the rear for next season. I have a perfect set of custom billet machined wheel spacers that put the correct rear spacing back in your Sy or Ty. The spacers are high quality made by Vette Brake Products. They only have approx 500 miles on them. They are complete with lugs and hardware. Just bolt them on w/ your wheels and go!I paid $200.00 for them, I am selling them for $160.00 + shipping. I can E-mail you a picture of the spacers if you like. Very nice pieces and make the 17" rims fit on the truck just like the factory wheels. First come first serve I only have one set. Bye Dale
