32 grill shell on Model-A

I have to install a 32 grill shell on my model A. In this picture, is this a standard 32 Grill shell? Just trimmed at the bottom for clearance for the frame rails and the splash apron? About how much was the trim? How did you determine that? I am hoping to use my Walker 28-29 Radiator in it....

 

I trimmed about 1/2" to provide plenty of clearance for the fenders. As I recall it mounted to the Model-A radiator just fine. And yes, it's a standard reproduction shell and grill.
