Only the grid caps coming from under the chassis (typically come through a corner of the shield or inside the base ring for the round ones) have to be inside. Those coming out from above (from the tuning caps or from IF/RF cans) or those coming from under the chassis but outside the shield perimeter (it is pretty intuitive: they cannot be easily put inside the can) should stay outside.

I have not seen more than one wire inside in the radios like 630 - I recently finished 620, which is similar; I think there's just one and it is the 75.
