I'm swapping axles out and can't reuse my ext. Ford radius arms, so I plan on building my own. I've seen all the other manufacturer's Y-links/radius arm designs, but can't seem to find the answer to couple questions. Is there an optimun angle for the upper to meet the lower at? Can I run the upper to the frame and have the lower meet the upper? I plan on using 2x2x.25 square tube, but 2x2 seems kind of small, would it be overkill to sleeve it with 2.5x2.5x.25?
 
how much lift? how long are the arms? why wont the old ones work?
 
I'm trying to keep it under 6" of lift
I'm shooting for the arms to be around 40"
The old one's were the Ford radius arms:

There's no where to put the wedges on without cutting way to much of the housing. SO, I'll be nothing the housing and using ballisticfab's radius arm brackets with coil mounts. To keep costs down, I'd love to be able to just reuse my arms, but I don't see how it'll fit.
