I have a 97 accord coupe with about 160K. When locking my power locks,
the door lock actuator in the passenger side door makes a loud buzzing
sound.
I took apart the door panel and looked at the necessary steps in
service manual.
I have the option to buy a replacement actuator or a new latch with an
actuator already attached.

72115-SV2-003 ACTUATOR ASSY., R. DOOR LOCK $88.45
72110-SV2-013 LOCK ASSY., R. FR. POWER DOOR $136.53

I would prefer to buy just the actuator and attach it to the old latch.
(would save me about $50). Can anyone attest to the difficulty in doing
this? Or is it best to replace the entire module (latch + actuator
completely assembled).

Also when removing the outdoor door handle (necessary to replace the
actuator), there are two bolts (accessed from inside the door) any tips
in how on how to remove the hard-to-reach bolt?
