ESS 650 VT2 Kit - A/C Belt Issue?

So, I'm running into a problem with the install AC belt-wise.

The car is a 6MT and I'm not sure whether or not the belt ordered is for DCT or not.

Part number on the current belt is BMW 7 841 529 6pk 1100m and it's much too long.

Has anyone with a 6MT installed a 650 kit and run into this problem?

Also, important to note, my car is an EARLY production 2008 model. I know that some things switched belt wise after 4/2008. Just trying to find some definitive part numbers...ugh.

Is the belt you are trying to use double sided? I believe the early 08s had a single sided AC belt.

They did, but that's not the issue. The belt that the kit comes with is too short (it's definitely the one that ESS includes in the kit - 6p 1000m).

From what I see, the OEM belt for the early 2008s is 6pk 1067. Also, too short for the bigger pulleys that come with the S/C kit.

I looked at Turner Motorsport, and they have two separate belt kits for the 2008 (pre/post) that you can get for their power pulley kit. I'm pretty certain that there must be a difference in size in there somewhere.
