21 stud main bearing help and questions

[hotrodjay]

I'm a new member here, my handle is hotrodjay. This is my 1st post. I have a 37 21 stud flathead v8 (pumps in block). I pulled the pan to clean out the quart of sludge (been sitting for decades). Uppon doing so i pulled the rear main cap because i noticed there was no oil slinger seal in it. The block does have the upper seal obove the crank. Nothing in the rear main cap. I did notice a "68" hand stamp on the cap; I think is 1936 only? Is there no slinger seal for this cap or do i have the wrong one??? I have pictures but how do I post them...lol
