pass side exhaust manifold

OK. My column was already installed so that explains why you can get the drivers side in and I couldn't, but I have no idea why I was able to get my pass side in and you can't. I have the heat riser on mine as well. I didn't even nic the paint it went in so easily. If you don't mind me asking, what is it that is getting in the way of the install? I'm just curious.
If you want some help one day, just ask. Oxford is pretty close to Trumbull, and I'd love to see your ride too.
