I'm sure that would work pretty much the same.
Just make a piece like this and mount it on the lower spring perch on the Toyota axle.
Then just buy a new perch for the other side and weld it on.
The one of the left is for the spring perch and the one on the right is the U bolt plate.

(If you would like a better picture of this, let me know and i can Email it to you.)
