can i use 73 duster lca for my bbp disc swap in my 65 valiant?

I have lcas out of 73 duster along with brake set up.I was wondering if i can use the lcas from the 73 in my 65 valiant.I understand they are the same length in all abodys? but with the early a bodys is this a problem? i want to put the new lca bushings in 73 lca now so it will be quick for the disc brake swap. :happy1: thanks in advance for advice! If they wont work i will just use my 65 lcas thanks.:burnout:
