i have a 1965 mustang and a 1966 mustang coupe. we just installed a elderbrock water pump and put all the bolts in but we found two holes where it appears to need bolts but has no threads in it when we added water in the raditor it leaked out the holes. Does any one know what to do with these holes am i suppose to add bolts in these holes. Please help i want to get this car back on the road again.
