'84 xvz12d Royale need brake pad spring

[garyS-NJ]

Took apart brakes on recently purchased bike and found front brake missing the flat bent pin spring thing that puts tension on the pins and pads.. anyone have one? Oh and I had regular cotter pins retaining the brake pad pins so I need to locate them... and while we're at it, seemed like endless air bleed the front linked caliper so I think I have a leak at the union under the frame neck.. with this I'd be inclined to delink the brake system simply by plugging the line at proportioning valve (or ditching the vslve) & adding a second brake line to the front brake master to the left caliper.. oem line source? & what, a longer banjo bolt at master cylinder?
