I am going to replace the seals in my upper and lower but ran into a problem removing the Ball Gearcase retainer. Two bolts snaped due to corrosion and I still cant get the retainer to come up. I have read both the Clymer and Seloc. All they say is to remove the (4) screws and then pry it out. <br /><br />Is there anything the books dont mention??<br /><br />Also can I replace the bolts with SS Bolt with anti seizing compound?
