underslung hairpins

Been searching this for sometime and can't find that anyone has ever asked this. I am putting a 54 Olds rear under my 27T coupe using an A top mount spring. The frame is zd 4'' in front and 8'' in the rear. With the tires I am running, it sets almost level with about 8'' ground clearance. Here's the problem. I want to replace the split bones with hairpins but they need to go outside the frame because the floorpan has been dropped for headroom. The channel job has the body tight to the outside the frame. Now I can drop a front mount from the frame,but if I do, the hairpins won't clear the frame/body Z if they are centered on the axle housing. The short wheelbase makes it possible to live with 5-6'' clearance at both ends.The rear scrub line requires no less than 6'' So, what will the consequences be if I drop a bracket down from the housing for the pins? The top bar would be 6'' below center and the bottom 10''. The rear suspension travel is only 3''. Pins are 44'' long. It will have a panhard bar

Doesn't leave much ground clearance at the rear axle attachment. How about just anchor the top bar even with the axle centerline and the lower at 4-6 in. below that. Angle them down for a bit as they leave the axle bracket ( first 12" or so), then run them parallel each other to the front anchor point. Using a non symetrical bar setup. Top bar longer and anchored to frame pivot with bottom bar joining about 4" back. A gusset added just where the tubes start to run parallel.

I did that on my daughters 'T' bucket(very low car) and it looks good.

I'll mock that up and see how it looks and clears. Thanks
