Will a convertible top on 2001 chrysler sebring lxi interchange with 1999 jxi?

It's unlikely a convertible top from a 2001 Chrysler Sebring LXi will directly interchange with a 1999 Chrysler Sebring JXi. While they're both Sebrings, there were likely design changes between the model years that affect the top's frame, attachment points, and even the material itself.

You'd need to check the part numbers for the convertible tops (or better yet, the entire convertible top assembly) for both cars to be certain. Even if some components *might* seem similar, differences in the way they attach or the dimensions could lead to significant issues with installation. It's best to stick to a top specifically designed for the 1999 JXi to avoid potential problems.
