Been there, done that.  Went to a local nut and bolt joint claiming to have
darn near everything in threaded material, and they never seen anything
like them leg bolts you speak of.  Call Samick at 1-800-592-9393 ext. 65
(don't wait for the dumb recording, just punch in the numbers) and leave a
msg or talk with Dean.  Order two longs ones, and the rest short ones.
That used to be a set for the SKG 400's but they've changed to all the same
length now.

Please don't.  Pursue all other avenues before doing that.  The T-nuts are
cast iron and should you mess up the threading process on just one, you've
got a mess on your hands trying to access the T-nuts in the keybed.  It
involves removing the keybed, .............  big hammer, breaking the glue
joints after removing the screws, not a problem for an experienced
PianoDisc installer, but if you've never done this, it could be
intimidating, not to mention LOUD!!.  BTW, the new T-nuts in Samick
products are cast aluminum.  They cross thread really nicely.  I'd imagine
after 30 years of the leg bolts (steel) reacting with the aluminum
(electrolisis I think) that either the T-nut would shatter or the threads
would crumble to little tiny pieces when the bolts are removed.  Any
comments out there about this??
