question for 41-48 woodie owners

[41woodie]

I'm repairing and refinishing the wood on my 41. In doing so I'm trying to remove the metal brackets that secure the roof to the B,C, and D pillars. I've removed all of the machine and wood screws visible from inside the car from the B pillar bracket but it doesn't want to come off. I'm trying to remove it carefully as I certainly don't want to damage anything by applying too much pressure. Are there additional screws that come down through the top into the back of the bracket? These would not be visible from inside the car and would require removing the top material to access. If such fasteners are present I'll have to decide if removing and refinishing the brackets is that important right now. I really want to go on a fishing trip removing the top covering to find screws that may not exist. Thanks
