Top too short?

Convertible tops can shrink. My brother has a 57 Lincoln Premiere Convert. When ever hes not driving it he leaves the top up.. One year he forgot to and when he went to raise the top it wouldn't latch until it got warm enough to stretch back out. Yours looks like what he had going on. Also talk to a good automotive upholstery shop that works on convert tops and see what the say. They might say the same thing.
