Hi,
I have the CMK set for my IV E aswell.... looks like it will fit just fine... From the IV D to the end of the war was the IV series equipped with the maybach 120 TRM motor...
I have to admit I am really impressed with the detail of the motor from CMK really nice stuff.... (I have seen one in person at the Panzer museum in Munster and it looks spot on!)
Hope this helps.....

P.S: forgot to add..... I don't have the full interrior set, just the motor, keep in mind the interrior set is for the H, J version which had the longer gun.... the ammo storage is differnt between the IV E and IV H,J
