I have one laying around off the back of a 99 Suburban 1500 but it is just ben't wrong. I am going to try and find something basically straight without the dogleg ends.

My suspension
Am do just about the samething on the rear of my '27 sedan, only adding split wish bones, other wise it looks pretty much like yours.Just hope it works as good as it looks. Sure turned out to be a lot more work than coil overs but yet sure is a lot cheaper. HEY, a buddy of mine and myself have a bid disagrement on my front axle. It is a 5" droped strieght. I say it needs to lean back 4-7 degress, he say's it needs to lean forward 5 degress. Who is right? ...Joe

Leaned back is positive caster and is what you want. Leaned forward is negative caster and will render the car undriveable.

I'll play Devil's Advocate for a minute. I think a single leaf in the bottom is too weak and flexible. If this were a full spring with 5-7 leaves it would be ok IMO, but I think wrap up and movement will be a real problem.
Posies told us we could run their quarter eliptic setup as the sole lower control bar on the setup we used in Dan's 30, but we didn't want to trust it, so we did the fourbar routine and simply used the spring as a spring.
Maybe you are planning to add more leaves, and if so I think that would work. Here is a picture of the setup we ended up with.

Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
