Bilstein 5160's and two left-rears

Hey, guys! A few months ago I ordered 6112's and 5160's from Rogue Offroad. I'm preparing to install everything next weekend and just opened the 5160's for the first time. While opening the box I observed both labeled "left rear". I thought to myself "no way" and continued opening them. Sure as hell I got two 379's (left rears). I have not been able to get ahold of them today since they're closed on Sunday. Gonna go out on a limb and say my Saturday installation is botched

What's the difference between the two sides? Can't find a ton of info about it...

 

You get these figured out? I think I read that this is correct for the 3rd Gen?

 

I did some research and posted in the 6112/5160 thread with a couple responses. For all intents and purposes, there is no functional difference between the sides. The rear passenger side comes with a spacer for the brake lines but, prior to Billstein including this on the earlier gens, it looks like dudes were using washers to make their own spacers. My install got pushed back and we're gonna get it all knocked out on the 29th. I'll report back here after the install. Thanks!
