door handle

[robertish]

hey all. new here.
ive got a 1982 gmc sierra and the plastic part of the outside door handle broke off.
Ive been to a couple of pick and pulls trying, but i cant seem to figure out how one removes just the little plastic button part. I have an easy time opening the door and can get as far as having access to the whole outer/inner door handle contraption, but cant seem to figure out this simple little task.
feeling a bit dumb but, i bet one of you has a trcik.
thanks a bunch.

also, if anybody has a diesel and wants to know more about running on veggie oil, i have some insights and personal experience to share, ive been running veg and biodiesel in the two tanks respectively. its been going pretty good aside from a little bit of trouble with the fuel pump in cold weather.
