Broken frame options: possible swap, or fix it?

The frame on my 310-8 broke where the transmission mounts to the plate, similar to the one this thread, but mine are big cracks, and the bottom of the plate in between the bolts/cracks is shoved forward about 1/4th an inch:

It looks like it had cracked before, and someone repaired it with a piece of metal across the bottom, and then I broke that so bad I can't even shift into gear now.

I found a frame from a B80 for $25.00. My original plan was to see if the frames were the same, and just swap everything from mine to the other frame, if that was possible. That'd give me a chance and excuse to clean and paint everything. But honestly I'd probably run out of time, and never finish if it took more than a weekend.

Then I found a like to this post and after seeing the different repairs, braces, and plates, I thought that I might be able to just fix my broken frame, and brace it so that it can take the dirt work I'm using it for.

My questions are: Would everything from my 310-8 attach to the frame of the B80, and would it take more than a weekend to swap frames?

Or would it be better to just repair what i have? I have no welder or welding experience but my brother-in-laws step-son says hes a decent welder, and his dad has a welder. I do have basic tools, a big hammer, a sawzall, and a grinder.

I was thinking something like in the attached image would be doable, and a good idea to beef up my 310-8, and 520-H with Front end Loader, as long as it's the same set up. What does anyone think would be the best route? What about the easiest and fastest?

Fairly easy repair for an experienced welder. I would suggest repairing your frame as compared to swapping in a different frame.

Easiest and fastest is definitely to weld up the frame, and possibly add/beef up braces around the area to enable it to handle the stress you are giving it.

From briefly seeing the specs for the B80 vs your 310-8, I wouldn't expect the B80 to be any better (it'll be similar or not quite as strong as your current frame), so I would expect the B80 frame to also wind up having problems with how you are using it (assuming you can swap everything over to it).
