I am getting my 62 BT7 ready for new metal and painting. I have run into a problem trying to remove the trunk handle. The Phillip screws came out with no issues, but the slotted screw that threads into the square shaft that runs from the lock assembly is not moving. I have tried spraying WD 40, but it is difficult to get to the threads. My last resort is to drill it out. I believe I read somewhere that this screw is hard to replace. Moss shows the screw and handle as one unit. Any tips appreciated.
