Gasket kit for 90degree oil filter adapter

I installed a 90 degree filter on my 5.9 Magnum, and used the Superformance gaskets. When I fitted the adapter to my block and found it needed a bit of grinding along the outer lip of the adapter for it to fit properly into the block opening. You may want to check yours by loosely bolting it in place with and without the gaskets to ensure the adapter seats fully.
