Disc conversion question

Are you saying everything but the spindle is dart? It looks the same as mine but the spindle is disc not drum. I'm sure once I take mine apart it will be obvious. Thanks for the help
No, he's saying what you have is not what you have been told. He is saying that what you have is all A body, just exactly like you would want for a bolt in. Re-real what I told you. Not sure what you have for an upper CA, you may or may not need to change that depending on the drum brakes you have. You should not need those lower arms.

Also, if you don't have, run over to MyMopar.com and download the two volumes for the 73 factory service manual. That manual GOT there because of some of us on HERE
