I meet Patrick and his wife Danese in there shop 3 weeks ago and they helping we with all my questions to restore my engine. I think the best way is to mail Danese Dykes ([email protected]) and ask her. They have a short blue catalog and i think i remember me there is a special fan on the short pump you can order! Or you can look online in the catalog, go on the Homepage.
If you need more help i can check my copie and try to find the partnumber.
