Oven element replacement- Simpson eziset electric

Question

I believe the element has blown on the base of my oven. There is a hole where the element appears to have cracked open so Im going to try and replace this myself. I have purchased the new element and had a brief look at the set up inside the oven- can anyone give me a general idea on how I might go about this? Do I have to access the elements from the back of the oven? Is it a case of just unscrewing old elements and s******g in new ones?
