Thats your flywheel and no youre fine thats how they all are. Unless of course im forgetting the dustshield on the back of the rear trans mount

 

There's normally a small cover that is held on there with two small bolts, but it doesn't matter.

 

2005 cobalt ss/sc standard transmission . Just wondering if someone knew the spec of it because I'm trying to buy one off eBay and want to make sure it's the correct length and splines on each end . Also if you could send me to buy the hanger bearing it goes into and the half shaft it connects to . Pretty much from the cv joint to the transaxle I want to buy
