I actually used to have that same Milli Vanilli record. It got filtered out of the collection when I came to one of those "storage space" crossroads, way back when. I got the "Checkout" record, which I mentioned above, and it is a great look back at how "high fidelity" enthusiasts got a grasp on how good their setup was. The narration is classic and it is a delight to listen to. It even came with a stroboscopic disc for checking speed accuracy for 16, 33, 45 and 78 rpm, to be used with a basic fluorescent light, as well as a graphical chart for recording the frequency responses of your system, using a sound level meter. The record is in great shape and I'd recommend this ebay seller any day, as well.
By the way, I also confirmed that the gray connector is the left and the black is right.
