The adafruit 3.2″ 2616 fits very well. It has four mounting holes that have to be removed. You also have to file the left and right edges just a hair and it should fit snug. After it is in place you will need to change the overscale options. Edit the /boot/config.txt and you will have to remove the #s from the overscale lines and play with the overscale sizes. It does take time but I do not remember the sizes at this time. I hope this helps.
