I had a three leaf steel one on the buick I sold recently. That was installed maybe 6 years ago. At the time, I found it from JCWhitney online I believe. I tried to order it and they refunded me saying they no longer carry it. I somehow got them to cough up their supplier and it turned out to be a local shop to me, so that's where I got mine. I was appalled that they had them already made for this application. Either way, you might have to special order. Due to the size and weight, I'd recommend a local spring shop. The ends are very simple, they're just flattened as to ride on top of the pucks in the knuckle pocket. I mounted it with the original rubber that I scraped off the old leaf using longer bolts to reach around the three leaves.
