After quite a high mileage the one of rivets holding the body to the chassis on the drivers side has worked loose. It's the last one that actually fixes the body to the base. I have carefully drilled the thing out but it would appear that the hole has worn slightly large - probably too much to take the same diameter blind rivet. Not sure if to start a new hole near and use a fresh same sized rivet or if to go with a larger diameter in the same hole. The factory went through a period of drilling through the outer body and into the base / chassis tube. The chassis tube is steel ad I worry about dragging steel into the Aluminium and causing a galvanic corrosion - which I know will be impossible to stop. Has anyone else had this and have any suggestions for a good fix. Many thanks in advance and Happy New Year to everyone!

I would use the same hole..larger rivet or same sized rivet with the correct ID washers mentioned below. .
Additionally, you can think of one or some of these> None of these will prevent the ultimate reaction, though they will retard it;
1. Insulation of the metals by using a plastic washer
2. Introduce a sacrificial metal, such as magnesium or zinc washers.
3. With the codicils above, consider using replaceable parts, nuts and bolts and expect to replace them regularly
4. In all cases, use your favorite spray like

This also applies to the Aero people body fittings and wherever the Factory pierced a galvanized chassis for any reason. Different strokes for different folks.
