Trade Two 14x7 Slots For Two 14x6 Slots

I have a nice pair of 14x7 slots with 3 3/4" backspacing. There is no brand on them I can find. I would like to trade the two 14x7 slots for two 14x6 slots with 3 3/4" backspacing, because I would like all four wheels the same. First, here are the 14x7 slots I want to trade. All four of these are 5x4 small bolt pattern.

Here are the two wheels I would like to trade FOR. These are 14x6 3 1/4 backspacing Original Fenton Gyro wheels. I don't necessarily have to have Fentons, as long as the slots match the style and measurements and condition of these.
