Hello and Welcome to the Forum family . If you will post your engine needs in the " For Sale / Wanted Forum " you might be able to source some parts . Ebay is your friend for used parts ,though in your case shipping might be costly . Some supliers might have OEM parts but they are getting scarce because of age . Most folks will suggest you just source a used engine rather than the hassle of splitting the case and doing a proper rebuild (if you can find the needed bits ).
I wish the best of luck in finding what you need to repair the engine . Please enjoy the forums here and visit often .
