67-71 back half in a 47-53?

[Thalcomb]

Im new to the site and would like to say hello to everyone, the site is great and has been a big help already. Now with the question, I would like to back half a 67-71 half ton with the coil spring/trailing arm rear end and mate it with my 53 half ton. Has any one done this swap before? Is there a better option than this? Right now i have a 70 nova rear end with leaf springs and would like to get away from the leaf springs. Any help would be appreciated thanks Ty.
