They are correct, the diff's are in backwards. All you have to do is take your bulkheads apart (a pain, I know) and rotate the diffs 180º on the driveshaft input axis. So if the ring gear is on the left, you will rotate it so the ring gear is on the right. If only the front is reversed, then only do the front. If only the rear, then only the rear. If both, then both. It's easy to put them in backwards and as many times as I have installed them, I can't remember what way they are supposed to be installed lol. If I had to guess, I would say ring gear in the front on the right, in the rear on the left. But I can't remember if the transmission reverses the direction of rotation from the engine to the output driveshafts.
