1970 F100 rear end swap

[Cosmicflyboy]

Hi all!

Needless to say, I'm new here. This might take a bit of explaining so I can get to my questions. I have been given the old family F100. Been in the family since new. It has been sitting since maybe 2005 or so. Well i'm looking to put a light duty overlander RV together. Yes, it would be easier to just buy newer super duty or something like that but where is the fun in that. Plus I am overly sentimental and also a proponent of up-cycling when possible. I think this truck is a good candidate. So motors i'm good with and body work i can get around...but i've never touched drive trains outside of brake jobs and the occasional ball joint change. For this project i know i'm going to need a heavier rear end (and possibly front end). I have no idea where to start. I will most likely be junk yard hunting for parts to build off of. I have no clue where to start. So i figure the collective knowledge of the internet ford fans could certainly give me a hand.

The truck has a 302 and is automatic. If i could get over to the farm where it is sitting i could be more specific...but during this whole pandemic business i'm not going near my over 70 Aunt and Uncle.

So my question, what are the best heavier rear ends (and probably front ends) that would work for this project?

Thanks in advance!
