Is it possible to leave the cap on when you replace the floor? I bought an 86 sunsport recently. The po started a refurb about 10 years ago but stopped part way through upholstery. It's been sitting since 97. Believe it or not I hooked up a gas can to it with a new battery and it started on the 3rd try. However, the floor is shot. The top was fiberglassed but the bottom was bare. The stringers seem to be in good shape except for the crossmbers which weren't glassed either. I have the floor out along with the wet foam. I live in an apartment complex so this is already a pretty big project. I have no way or place to store the top cap. Can the floor be replaced without removing the cap? I don't want to do a half a$$ job.
