Seat screws

[Sjhcobra1@cs.com]

I'm rebuilding the seats on my Mk2 and can't locate the long screws needed 
for my project.  Rick and Curt are both out of them.  I'm looking for 
1/4-28x2-1/2" fully threaded flat head machine screws with slotted or 
phillips heads in either zinc plated steel or stainless steel.  Anyone have a 
lead on a source?  Thanks!
