E159 spark plud access

I changed 6 on my 8 plugs today. I accessed the 6 plugs I have changed thru the interior access. I need to get to the 2 on the forward right of the engine (#3 and #4). They are angled forward on the right (back on the left) and I cannot get to them from the interior access because they are to far forward and the space between the head and access hole is to tight. Plus, I have two 1-inch hoses right at the edge of the access hole. I tried to get my smallest ratchet in the space between the head and opening and could not. Special tool?
I thought I could access the #3 and #4 plug thru the wheel well by removing a panel (like my explorer). The wheel well is all structure . Do I have to pull the alternator?
Any experienced help would be appreciated.

Thanks
Bill
