spoke length

does anyone know the stock spoke lenght for a 77 KZ750B (twin)
it looks like the same wheel of a KZ650.
building the wife a trike and the donor bike was pretty ruff. rim and hub are ok, but the spokes are toast.
any ideas on lenght?
thanx

At the buykawasaki.com web site, it shows a different
length and part number for each.
