Using 65 Newport BBP set up on my Dart?

if you have the new axles made with BBP B/C/E or truck/van spacing then you should be good.

most (if not all) C-barges came with gargantuan 11" drums that are heavy and some of the brake hardware/shoes can difficult to get a hold of and can be spendy. so just know that going in.
what's a half inch between friends?

(imma go back and edit)
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.
