The 14FullFloat rear has big hubs that stick out, similar to the ones you see on the front but sealed with bolts. A 14SemiFloat has a flush mount serface where the wheel mounts.
Here is a pic I just pulled off Google, this one has the drumbrakes but I would conver to disk, there are many who make a conversion kit to disk. Thoes drum brakes are HEAVY!
I would show you pics of my 14FF w/diskbrakes but my club's website is down and my gallery whent down with it
Google images is a col way to find pics too
