Even after speaking several times to the great folks at Boogie, I cannot get the chassis out of the head in order to slip it into a spare combo shell I picked up. I removed the long 'safety' screws going thru the chassis, along with the four screws going down from the top of the head. Somethings getting caught up as I try to slip it out the rear, and I would gladly slip it out thru the front, but the front panel seems to be stuck on (yes, the 4 front screws have been removed!). Any thoughts?? Should I lay the head on its front & gently hammer the front wood panel from behind, assuming it wasn't designed to be glued in place!!?? I"M BAFFLED!! Thanks all.
