No, they don't fit. The top of the 32 Commercial shell has a different couture than the passenger grille shell . HRP
I remember taking a photo of of my truck and a extra passenger grille side by side and I finally found the photo, hopefully you can see the difference in the two shells. HRP
I see that there is a peak made into the commercial grill. I can't see any other major difference just from the pic though. Look how the bezels are concave underneath. Looks like the peak shouldn't be a problem.
Where there is a will there certainly is a way, if you look closely at the photo of the two shells side by side you might notice the commercial shell look to be flatter across the front and the passenger shell has a more rounded look, that is where the tip of the bezel just under the Ford oval wraps around the shell, the commercial shell lacks that protrusion. I'm not saying it can't be done but I would think there would have to be some modifications to the grille itself or the bezel to make it work and look correct. HRP
On my last 2 deuce pickups I grafted pickup tops to passenger shells for a unique one of a kind look. Something different.
My pal Dave just used a passenger shell on his confused pickup. HRP On the other hand Steve's pickup has the commercial shell.
If you want something else for a different look, I have seen a 34 truck stainless grille molding fitted to a 32 truck grille and I liked it.
