Custom lower control a-arm for 1937 Buick

[Mutt's37Buick]

So here is a new approach I'm exploring to allow the front suspension upgrade:
http://www.crankshaftcoalition.com/wiki/1937-1957_Buick_Oldsmobile_Pontiac_suspension_upgrade
The roadblock that I ran into is that there are no lower control arms with ball joints that I have found that match the dimensions of my '37 Buick Roadmaster (20" long arms). The wiki is focused on coupes that have 18" lower arms.
I have considered having a ball joint mount plate welded onto the existing arm.
I have considered making a transition plate that is bolted, or welded, to the frame to attach a shorter arm (probably a Chevy C10 truck lower arm).
Another option may be to have a custom lower control arm built that matches the current geometry.
1) Does anyone have a company they would recommend to build a custom lower control arm?
2) Which approach do you all think will have the best results.
Thanks
Mutt

Honestly IMO, in the long run I think you'd be better off to clip it!!
That way you have no specialty parts and any modern brake, steering component you could want!
There's a reason that everyone does it that way, (why rethink the wheel?)
