" From: Wrambler242@xxxxxxxxxxx " " They are/were spec'd for the W100 4X4 trucks that did not have the hub sticking thru the center. " They ran a 5 X 4.5" bolt pattern and while they bolted to the rear of the hub on the doge trucks they came on, they are machined front and rear. They will slide right on a drum brake hub too, but, like I said the rotor thickness is way out of propertion to the diameter! hmmm... the only one i can find in my napa book is their 85743: http://www.napaonline.com/NOLPPSE/(S(nabzmbjk3yyitk3srabsxur3))/Detail.aspx?R=NB_4885743_0148375486 Attributes # of Bolt Holes : 5 Bolt Circle Diameter : 4.5" Brake Rotor Diameter : 11.75" Brake Rotor Discard Thickness : 1.18" Brake Rotor Thickness New : 1.245" Brake Rotor Type : Disc Brake Rotor Only Center Hole Diameter : 3.254" Height : 2.635" Maximum Lateral Runout : .004" Mounting Type : Type M - Rotor Only. Rotor Is Attached To A Splined Hub By Studs That Are Pressed & Swaged/enlarged On Their Outer Edges To Hold Hub & Rotor Together. Replace The Complete Assembly If Hub Flange Is Bent Or Damaged. See Diagram For More Information. Vented / Solid : Vented this looks a lot like a 4wd version of the 85558. the 85877 looks similar, save with 4" ctr hole and 5.5" b.c. none i could find are anything like 1 3/4" thick. ps. http://www.napaonline.com/MasterPages/NOLMaster.aspx?PageId=801 gets you straight to the PartsProSE catalog which you can search by part, keyword, or interchange.
