    I have couple year old calipers on a 81 Blazer thats dead. Can I put those on my 73 K20?? Or would the older 3/4 ton 8 lug have different calipers?

    the bolt that holds the break line to the caliper (i think its called the banjo bolt)is diffferant. the blazer calipers have a 10mm banjo bolt and the k20 has 7/16's

    But you can use the brake line off the '81 with the calipers and banjo bolt from the '81 and it will work perfect on your '73 :thumb:
