A body .890 / .920 '' torsion bars

I am looking for a set of .890 or .920 '' torsion bars for my project. I see them on pST but they are 300$ + .
Any body have a good set ?
Thanks,
I am at the begining of putting my 440 in a 69 Dart. Heard it is going to get interesting .......
Picked up a set of Shumacker mounts already.
Up for suggestions with headers ...

I have a set of 890 L & R on the ground right now if you're still looking
