I have a pair of Landrum leaf springs on my 69. The guy I bought them from said they are 200# in their current configuration. Ride height is pretty good. Maybe a touch high for my liking. Sits about like a 1.5" drop. I'm hoping as they settle in they wil drop a bit. He said he had talked to the company and they told him if you remove the bottom leaf it would drop the rate to 175#. I might give it a try one of these days as the 200 is a bit over the top.
