Vintage Synth Repair

Hi all,

Need some advice regarding a problem with an Orla XM600 module. The 
problem is not really directly related to the module, but could 
probably be a problem with various other modules or synths.

The display for this module is a small board which is attached to 
the main board at the 4 corners of the display board. The display 
board mounts to the main board by pushing the 4 holes down onto 4 
expanding plastic pins on the main board. These 4 pins are broken, 
so the display board can no longer be attached to the main board.

Are these plastic type pins something standard, and is there some 
way they can be replaced. Or if not, can anyone suggest an 
alternative attachement method for the display board, other than 
duct tape, of course!

Thanks very much,

John
