Like to replace all my post screws but cant find them at any hardware stores. Marco Specialties have them (refer picture) but they only fit 70's ems which measure #5 x 1-1 1/2". The sixties ems are slightly longer #5 x 1-1 3/4" to 2". The smallest I can find stop at #6 size.
Any ideas where I would get these screws ?

Would the GTB A-8857 Post suit?  If so RTBB have them.  This is the wood srew type that fits the acorn nut on top to hold down the playfield plastic.  Or is this too short?  This is shown here http://www.rtbb.com.au/catalog/index.php?cPath=40_125_126
