You will want to use the Missile body. The Satellite body has extra trim and such that needs to be sanded off in order for it to be correct for any of the SS/AFX cars.
I am not sure anyone is doing a AWB resin body based on the Moebius body yet.
I started one with a Satellite body a while back and tinker with it here and there. Mine is a Hodge Podge of parts to be a correct AWB mule car that had the Golden Commandos lettering on it. Because of this I am not completely sure if the MIssile kit had the parts for the AFX but believe it has all the engine parts there to make it including the headers IIRC with exception to the stack injection. The engine I am using in mine is based off of the Revell GTX Hemi and mastered with added in details then casted. (not available for sale) Uses Johan "Petty" headers, stamped steel Hemi K valve covers from Johan and cross ram. I was going to use a Hilborn intake also but decided on the unmodified mule car during testing. So before the Hilborn was added.
