Unbolt handbrake from car and then remove rivet
(1) Once rivet has been removed, pull operating rod (2) with pawl (3) attached from handbrake, via plastic knob end. The original pawl will need replacing by removing the flat headed rivet (4). The rod now requires bending true to plane, about 70mm from the hole end, down about 25mm. Although the new pawl (5) is a different shape you are also moving fitting points from top hole to bottom hole, hence a bend of 20-25 degrees.
Insert rod (2) back into handbrake before fitting the new pawl as described into the lower hole using the new flat headed rivet (4). Once rivet has been peened over, ensure it moves freely. Push plastic button in and fit domed head rivet (1). Before finally peening over to complete the work, check that the handbrake works freely and that the bend in the rod does not foul anywhere. Some people prefer to use a clevis pin instead of a rivet(1) for ease of removal. We find that grinding away the rivet is easier than drilling because the rivet may spin. Peening is done by using a centre punch in the middle and the outside burrs outwards.
