gt sts floppy frame

[i used to be faster]

Hi folks
anyone have any experiance with repairing the thermoplastic frame, my bb lug is loose.
. Had the crack welded but the play seems to have worn the plastic!!!!!!!!! I'm normally pretty good at bodge repairs as a last resort but i could or do with some help on this.

Got a mate that does a lot with carbon finer mainly for motorbikes but Im sure he could possibly fettle it if you want me to have word ?
