I make my own crank scrapers and use the stock Mopar stock stroke windage trays I open up the louvers on the side for better drain back I do use the two oil pan gaskets bewtween the scraper and windage tray, I cut one in half and glue it on the block up to the crank scraper, the scraper is glue onto the other side of the block and then one thick Fel Pro gasket on top of the scraper and half gasket, another thick Fel Pro between the oil pan and windage tray I have since started adding more drain back holes at every main cap like the one in the picture on the right side, I took this picture before adding those additional holes
