The coach that we bought (1976 Eleganza) had (not so nice) later model seats put in for the driver and passenger. We would like to go back to a set of original swivel seats. I have located an old Palm Beach model here in town that has been sitting being slowly parted out for the last 10-15 years that has a decent set of seats with the slanted top swivel base to scavenge. The problem being that the whole coach has sunk into the ground almost up to the outer frame rails, so the only way to access the bolts will be from the engine hatch. I'm not sure I'm going to be able to reach the bolts with my socket tools (for both the top and bottom) in order to remove them. Any other ideas? I'm assuming that the slant base is one piece with the plate attached by the 12 bolts? (It was hard to see for the old carpet and I haven't had time to rip it all away yet.) Could these be drilled out? IF so, what kind of drill bit will be the best for doing up to 24 bolts??? Any other tips?
