Hi Chris,
I would not worry. Its normal to see a little cracking of the conformal
coating on cap leads when you bend the leads. As long as its not
cracking along the main body of the cap you should be OK.
Also, the 2N7000 is probably OK. 6mm is usually specified to provide
clearance for other boards that may go above it at some point. Its not
super critical, and its OK to bend the leads as needed to get it close
to the board.
73, Eric WA6HHQ
