Putting a 318 together and something seems wrong here (see pic)

hmmmmmm.....I personally have not seen one (almost looks home fabbed).....that does not mean it does not exist, I am just saying I had not seen it.

On my 318, that part was not there ....just the thrust plate and all 4 bolts went into it.

my engine had an oil slinger (looks like a saucer) that goes on the crank snout and slings the oil as it rotates .
