Need help choosing carpet, low hump vs. high hump?

[The Big Green]

First off, I have a low hump. It's a '67 2wd that I Z'ed 2 1/2 inches, thus moving my floor up 2 1/2 inches. My rubber mat fit somewhat ok, but it pulled the sides by the doors in enough that when I by door sills I don't think I have a chance on it looking right. I don't know how much higher the "high hump" carpet is. Should I buy the high hump carpet? Any info from some bagged guys would be great, or just you guys that know the hieght difference between the two carpets. I have no carpet or mat now, it's just metal floor so I need carpet very soon. My feet burn from the bare metal floor every time I drive it
