The upper a-arm studs are likely larger on the 3/4 ton so the shafts might need to be drilled out to utilize the 1/2 ton arms as is.

The x-member is definitely interchangeable. I have a crossmember from a 1/2 ton under my 1-ton dually.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.
