Repair 69 Charger grille plastic

[Charger43]

Anyone know the best way to repair a center section of 69 Charger grille. Transplanting the big section left  of the I and 10 missing teeth
I got from a donor. The body shop that restored the whole grille over a three year period used Q-Bond from KTool International but it didn't last very long
and fell back out.
