7 1/4 to 8 3/4 rear end interchangeable parts

So I just finished the brake swap from the 7 1/4 rear end which had 10" X 1.75" brake shoes to the 8 3/4 rear end which also is 10" X 1.75" brake shoes. Everything fit great except the parking brake lever's they had to be changed, they would not allow the shoes to sit correctly on the backing plates and I also used the 69 Dart style adjusters and the self adjuster hardware. I disconnected the park brake cables from the backing plates of the 7 1/4 slid them out and just re-installed them into the 8 3/4. The reason I used the 69 Dart self adjuster hardware is because this 8 3/4 axle came out of a 69 Dart and I liked the looks of 69 setup better than the 66 style. I was even able to use the same drums that were on the 7 1/4 also. I had ordered everything new before I did this swap not knowing that just about everything is inter changeable. So for those of you who are doing this swap if the brake components are like new on your 7 1/4 which mine were, then you can use just about everything on your swap.
