Oh, there will be a C-clip on the rear. Pay attention to the thrust
washers. While you've got the drum out you should look at the condition
of the nylon bearing and replace it if it's getting badly worn so as to
do the two birds thingie...

Might look at the lower rollers/skid bearings at the front support, too,
while got it out.
