Sorry, I should have been a bit clearer.  I used a couple of the
inverters on the HCT04 back to back to form a buffer.  This way I
could buffer the clock/data/strobe lines with one HCT04.  Each line
came out of the PIC, into an HCT04, daisychained through 6 x HC595s,
then through another HCT04, daisychained through another 6 x HC595s ad
nauseum.
