Centerboard trunk width

Is the centerboard trunk 1 1/2" or 3/4" wide.  The planes are not clear and the kit came with two 1 1/2" x 3/4" pieces of wood for the ends of the trunk.

Thanks

It's a Skerry kit

The trunk is 3/4" wide to hold the 1/2" daggerboard. The plans show the 1 1/2" dimension glued to the sides of the trunk.
