Belt buckle metal repair (Burbank)

Hi all! I recently purchased a belt buckle that has a clip on the back that is too small.
The one that is rectangle has a clip that is too tight.
.
.
the buckle that has an oval has a clip that will easily fit my belt.
I need someone who can remove the old clip and replace it with a new metal clip that is the wider size.
.
.
and also do this without hurting the integrity and look of the buckle.
No scratches!!! I cannot take the larger clip off the other buckle.
I need someone to fashion a piece of metal for the smaller clip (I just wanted to be clear since some people have asked about that!) If you can handle this.
.
.
please let me know!!
