Rear End Swap to a Wider setup?

As a beginner to all this, I am thinking of swapping my whole rear end (1938 Dodge RC Humpback) for a wider one. My thinking is that a wider spread will give me room to use wider/larger tires for better traction and stability. What are the 'pitfalls" involved concerning function, safety, or anything else I haven't thought of? Thanks

There is only so much room in the fenderwells for tires. No matter how wide or narrow the rear end is you can only stuff so much tire in there without modifying the inner panels and/or frame (or jacking the car up which I hope is not what you're planning....).
By measuring carefully you can determine exactly how wide of a tire your car will except and order wheels with the correct backspacing to put the tire in the center of the well. Changing the rearend width is a lot more work then you have to do.
This a worksheet from the Chassisworks site.

It is used to determine the correct rearend width for narrowing but you can use it to determine the correct wheel offset and backspacing by plugging in the variables as you measure them from your car.
I know this can get confusing but doing it this way is much easier and cost effective then swapping to a different rearend which will gain you nothing...
If you have any questions, ask.

Rear End Swap to a Wider setup?

Thanks Astroracer. I want to keep the truck as original as I can. I was thinking that I could put a wider tire on it by having a wider rear end and widening the rear fenders to allow for the size difference. Do you think this is a possibility

Not if you want to keep it original. Putting a wider rearend in is actually going the wrong way. You need to put in a narrower housing so the tires and wheels DON'T stick out farther. This involves cutting and narrowing the frame also which is going hard against your "keep it original" statement.
Leave the rearend and fenders alone, do some measuring and stuff the biggest tire you can into the original fenders. If you do it right you can get a good sized tire in there without cutting up the car.
