Use a credit card (2) to remove the plastic caps over the top bolts. Slide them under the edges of the caps and press hard together. That will release the hooks on the bottom of the cap.
Flatten the holes back after removal. Pliers, screwdriver, hammer, etc. Dab rust remover paint on qtip and touch up holes. Use low strength, high temp loctite on replacement bolts. Buy new silver replacement bolts if you have old stock. Tighten lightly, very lightly or you will easily strip bolts.
