on my 88 dl wagon, i am replacing the front calipers and the top bolt is missing. I have new pads, axle seals, all I need are new c calipers and brake rotors. I could and probably will get the bolt at pull and save but every time I buy the bolts they disappear by the time I reach home.

should be the same as the bottom one, just take it to the hardware store, though they may not have a huge selection of metric 1.25 pitch (what most of our bolts are)

got the bolt but the caliper was too small.
