First off the reason for the being "pressed for time" is because I am active duty military... Trying to report to my new duty station ON TIME.

I was having rough idling issues while driving from Houston to Norfolk. It started in Louisiana just outside of Mississippi, so I stopped at an Auto Zone around Vicksburg, MS to get the OBD II codes read. I have misfire in cylinder 2. We are pressed for time as we are trying to get to Birmingham, AL by nightfall (to stay at my in-laws), and the guy suggests just "limping" it in and getting it checked in the morning. We do just that. I bring it to a local shop and they tell me it is a bad coil pack and the part wont be in for 3 days. I call the Land Rover parts department and they say the same thing. So I once again decide to "limp" it to Norfolk... aside from wasting gas, no issues. So I go to the dealership here to pick up the part (this is about 10 minutes before closing time) and I ask for a replacement coil pack, the gentleman behind the counter asks me if it is the short or long one. I have no idea. I do research and find out I need the long one. Today I return and low and behold, they have one left. JACKPOT. Now the fun part...

I get home and pull the old coil out... and compare it to the new one. This is what I see NEW vs OLD So maybe they will fit in and I only need a different set of bolts?... Well... this is the connection of the old one and the connection of the new one

has anyone else run into this issue?
do i need to replace all of the coil packs and get new wires?
should i just order an older style coil pack (as below)
