HI - I've got another question about gluing instructions for this same kit.  I'm getting ready to clue B37 to B38.  When I test fit with the front uprights in between the front uprights are loose - they aren't squeezed tight between B37 and B38.  Does anyone know if that is by design?  Or should I also glue the front uprights to the covers?  Yes, I know my progress is very slow, but I've had some hand and shoulder issues the last few months that has slowed this kind of stuff down.)  Thanks!! Jeff
