Years ago I saw a "how to" that started with a front sway bar from a C10 and modified it to work on an A-Body. This was _after_ we bought a hellwig, but I'd have done it.
As I recall, all that was done was cut the ends to length, then grind them flat, drill new holes and done.
EDIT: I guess it wasn't that long ago. Also NOT C10's....
