Using the 70%-100% idea, the lower links would be 26" or less. I forgot to dimension the actual length of the uppers.

If i kept the frame rails wider in front of the tires, or had a crossmember in directly in front of the tires, I could make the upper links longer.

I'm going to fiddle around with the drawing and see what i can come up with.
I usually try to get the uppers really close together on the axle, to help with angle/bar length and keep the roll center close the axle centerline. I've found we can get johnny joints down to 4" apart on center, and 3/4" heims down to 2" on center. If clearance above the housing is an issue, you'll obviously have to move them further apart to get them lower.
