1970 duster slant six 8.25 rear swap

My 70 swinger with a slant 6 .... i swap in a 8.25 from a 73 duster ( i think ) but it when right in with a set of 8.75 shock plates and new u bolts
But here what i didnt know ... YOU NEED TO SWAP OVER YOU E BRAKE CABLES .. PULL THE ONES OFF YOU 7.25 and put them into the 8.25 ..
Or it just be me :D
