My mainsheet block on the 383 has a bad sheave in it, the plastic in it just gave out from age. I am assuming I will have to drop the headliner to remove the bolts and washers to remove the bad block and then re-bed and reinstall the new block, etc. But before I dive into that, I thought it worth asking, is there a backing plate under there that maybe is threaded so the headliner doesn't have to come down? I am not looking forward to doing that with the rains we are having in our traditional Florida Summer! If headliner has to come down, any tips so I don't damage the panels or make it to where I have to drop several panels to get the one down?
