I think there are only 4 bolts, that's it. Quite simple. When I removed mine the 1st time however, those bolts were very tight. I suggest you use a breaker bar with the correct socket to initially loosen them.
Other that that, it should be quite easy.

it wasnt the bolts were that tight but they stick out of the bottom and that part tends to rust so when you are loosening it the rust swells the bolt size and you snap off part of the bolt
