I have some in the garage but they are not marked, they were quite low as I recall something like 350 and 450 lb/in respectively. I am pretty sure Nic or somebody else will know. If nobody responds I can measure the wire diameter, spring OD and coil count to calculate the rate. Some time in the late 1970's I had Hypercoil wind some replacements for me that are slightly stiffer but have the same coil count and spring diameter, they were marked as are all Hypercoils for rate. I can check and see what they are so you would have a ball park number, They were really expensive at the time so I switched to 2.5 OD after that because it is a common size for race cars.
