3490 x 1 set. The XK150 common "Wedge Shape" design handbrake pads to hand rivet with the 4 provided bi-furcated / split copper rivets onto the handbrake fingers. This is the commonest type fitted to XK150, but some feature a later, MK2 design quick-fit version that may have been retro-fitted SEE : 3460.  Original Number 8302. VBO 8072

NOTE: We advise that you examine the contact surface of the new pads to the disc and before rivetting them in place,  face them up to the correct angle to the disc for a 100%  handbrake surface engagement, as the fingers are always engaging at a diminishing taper to the disc as they wear.
