When I built my shifter, I used 3/4" DOM tubing, .120 wall. Plenty strong. The OD of the front shift rod is close to 3/4". I bought some 3/4" U Joints from ebay and welded, drilled and tapped various connection points. I re-used the front splined piece from the front rod. I bought 2 bronze console bushings and built a carrier for the rear shift pivot. I also bought a spherical bulkhead bearing bearing for the firewall.
Do you happen to have some pictures of the setup?
