I purchased a GC III a few weeks ago. When I took it apart I removed all of the slate screws (not realizing ofcourse that the slate is attached to a frame). My question is, does it matter if the head & foot slate is not matched with the correct frame? Also, is the slate supposed to be screwed into the table frame at just the head & foot or on the sides as well (to clarify, I removed 8-3 inch screws 2 head, 2 foot & 4 on the sides). Thanks in advance.
