Had a 2008 Sahara with running boards. Bought a set of Rubicon Rock Rails, swapped them and put the running boards in storage. Sold my 2008 with the rock rails installed and bought a 2013 Sport. Went to put my old running boards on and forgot that I don't have any of the hardware....Does anyone know what the specs are on all of the nuts and bolts for the Unlimited OEM Running-Boards or where I could buy them? I checked with Quadratec and they were a no-go

 

I just installed a set of Rubi rails on my 12 JK.

I went to Lowes and bought the following for my JKU...

x12 M6x1.00
x12 M6 nut
x12 M6 washers
x6 M8x1.25x30 (it calls for 25mm in length, but 30mm is all Lowes had and it worked just fine)
x6 M8 washers

For those with a two-door, then it's...

x8 M6x1.00
x8 M6 nut
x8 M6 washers
x4 M8x1.25x30
x4 M8 washers

Edit: I removed the comments about the u-nuts. I reread your post and seen you have a 2013, so your Jeep should have threaded holes for the M8 bolts. For those with 07-11 Jeeps, just know you'll need to add U-nuts to this list for the M8 bolts. '12 and newer have threaded holes where the u-nuts were installed on the 07-11 Jeeps.

Thanks for the response man, I ran to Home Depot briefly after posting this and managed to figure out the right bolts. Unfortunately, the middle threaded hole on the passenger side is not threaded right, goes in at angle, but other than that it was perfect.
