I have the center grille strip you need. It might need a little work but if you plan to paint it black, as original, your body work will be hidden.
As for your wheel, the 17" wire wheel from a '34, '35, or '36 Master Series car (6 bolt) should be the same as your truck. If you bought a 17" 5 bolt Chevy wheel, it is from a '34 or '35 Standard series car. I might have a decent wheel also.
Jim Carter now has new reproduction Stainless grilles for the '34-'35 truck. It might come with the center moulding or he might offer it as a separate item.
Only trucks with the deluxe package (in '35-'35) had chrome grilles and center mouldings.
