Hudson 8 tappet covers. '34-'52

Wondering if the shield inside the tappet covers, with the six  ears, do the the ears sit inside the block, or the covers?  I have found them located both ways, and inevitably the ears are distorted.  Currently working on a '48 Commodore 8 coupe with copious leaks out the side covers.  Thanks in advance for any thoughts,

    can you post a picture of what you call tappet covers with six ears ?

    Haven't got a pic, but I'm not actually talking about the external covers, but the internal flat plate that fits inside the recess of the  tappet cover itself.   This flat plate has breather holes in it, and six ears at right angles to the plate itself, about 1/4" long.  In most cases these ears are distorted and bent, and the plate does not fit neatly, so I am wondering if the plate goes between the block and the  gasket, or sits in the tappet cover itself.

    Thanks muchly, as I suspected the ears go inwards and sit inside the  block openings.

    So they changed the position in the Step-down years by the looks of it.  As you say, this fits perfectly in the cover.  thank you for picture jack.
