Using 65 Newport BBP set up on my Dart?

Thanks for all the replies fellas! Looks like I have options!
My donor stuff is def 5 x 4.5 and although I haven't looked at em in a bit I do believe the axles are tapered. I'll snap some pics of em in the next few days and post.
Here's the axles and backing plates from the 65 Newport......looks like the brake bits should clean up.
