bulb keel dimensions - sunfast 32i

[covers4sail]

I have a jeanneau sunfast 32i 2003.
I am currently about to modify a yard trailer that was built for a similar boat.
My question is...
Does anybody know the width at the end of the keel of the "bulb" on a sunfast 32I
I will have to beach the boat and measure if I can't get this information.
The existing trailer has 24cm(10") for the keel width.
Thanks
