Replacement parts for Xperia z3 compact

[blue-eye-boy]

Hi all,me again. my xperia z3 compact fell, and the back panel cracked. I want to replace it myself, there is a million videos on the net showing the procedure, cause it is a fixed panel.

The one shop in Polokwane charges me R450 for a replacement part, and on www.mobilephoneparts.co.za R280. Do you guys maybe know of any other places which sells this type of parts? Maybe the fleemartket shops?

Pls guide me. Thanks a million.
