Help me pic the right carpet.

[Mr Handy]

OK so I am getting ready to order carpet for my truck, I have a high hump and will be running an NV4500 so non standard shifter location. Obviously I am running a high hump and am buying ACC carpet.

Here is my question, what is the difference between a carpet for a turbo 400 truck and a 4 speed truck? Both have a high hump to my knowledge, does ACC cut the shifter hole? I would think the carpets would be the same with no holes, but they list two different part numbers.

I figured I would get an answer faster here than from ACC themselves.
Thanks
