So it appears you need the part for a '71-75 LeSabre or Centurion convertible.
GM did not sell the 9623941 handle by itself. GM parts books show the "folding top front roof rail lock" as an assembly of the handle, hook, and spring. Part no for the lock started out as 9835065 in '71 and was superceded by 9623939 during the '73 model yr.
Here is an eBay item from The Parts Place showing a reproduction 9623939 left hand lock by itself:
