Rear diff question

Much like the Mopar 8 1/4, the Ford 8" is a lot stronger than people give it credit for. But, axle availability is not good, unless you go custom like Moser, Strange or Currie. Keep in mind it has three pinion bearings, much the same as a 9" and that gives it some strength.

Lastly, if you find the ribbed center section, it is very strong. I have one in the 8" housing under my Mercury Bobcat.

Here is the heavy duty extra ribbed 8" center section. A lot of people don't even realize Ford ever made one, but they did.

It's all free including the wheels and tires to start with the only thing
There isn't a lot in my area for mopar and what there is is super expensive and I'm on a budget
My biggest reason to swap right now is for slightly stronger than the 7.25 and for the 5x4.5 bolt pattern it's basically all free the rear diff, the spring relocation mounts, the wheels and tires, and his help, garage, tools, and knowledge. The only thing that I have to pay for used the front rotors and pads for a 73 dart swinger and with all the input from you guys and what I've read elsewhere it seems like it will be fine for a start thank you all for the input
