I had the same problem, the clips appear to be distribution points. the left clip affects the left menu button and the left and up direction on the stick, and the right clip affects the numbers and remaining directions/buttons.
They are very important to the way the keypad connects to the motheboard. If you have damaged these they are nigh on impossible to get replacements for. I have asked SE if they would give them to me even if I was to pay, but they have refused and said I need to take my phone to a repair center which I really can't be bothered to do.
I would therefore look on ebay for a complete dead phone, and use the clips from that

In reference to the recent UFO crashing into a wind turbine up't north, suspected "an ultrasecret robot stealth aircraft project hinted at by MoD";
"El Reg rang the MoD for clarification as to what material it has which could be classified as more secret than top secret, but a spokesman said: "That's so secret it's beyond above top secret, I'm afraid." ®"
