I have a set of cal trac bars for 73-87 chevy trucks with the axle below the spring and at stock ride height plus or minus 2in. I am switching to a 4 link and have removed the bars and brackets but still need the spring eye bushings for setup and measuring you can buy a nother set from calvert or wait a couple of weeks and I wont need them and will send them out 200.00 shipped.
