I'm cleaning up some 1.54:1 rockers to swap on to my 1959 truck. I went to put the rocker stands back on the shaft during reassembly and they slid right on. My question is: Is the overflow tube going into the top hole the only thing preventing the shaft from turning in the stands? Or should they be tight on the shaft? Thanks for any help.
