74 to 65 Drivetrain Swap!

The front end seems to be in pretty good shape, and I’d rather not get into all that and have to replace suspension components and pay to get it realigned and such, remember I'm on a budget. I’m thinking that pulling it from the top might be the route I should go again I’m asking you all that have done this before.
Because I don’t know much of the history of the Cuda, it has later model front disc brakes it might be possible it had a K-member swap already. Can anyone tell me what to look for to confirm if this is the case? I’d like to know what I have before start buying new mounts and such and get only what I need to get the job done.
