81 Blazer calipers on a 73 K20

[trailblazr81]

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

well it has steel braided lines so the lines are being swapped as well!!!
