WW2PSYCHO - There were many different road wheels for the Sherman's throughout it's life. Not sure of any details of when or what wheels were used? You can try asking over in the armor forum. There are many that know about these M4's over there. Hard to tell from the real picture but it looks to me that vehicle has the open spoked wheels and solid idler? What options come with your kit?
In the picture many things may not be present because of the offload (and stowage while on the LST) of the tank. Once on land many things would have been mounted or rearranged.
