Your not offending me at all. Having a machine shop we tried it all Bronze Aluminum and several other materials. Unless you attach the LCA to the pin as Ceedawg shows. That arm moves off the pin.
The only reason for eliminating the OEM bushing would be for ease of travel up and down for weight transfer. There are many after market suspensions out there designed to do this . We were going to go with HDK. But bought a project car with an AJE suspension. If we had to do it over we would have went with struts for a race car due to no upper arms. I would recommend HDK for a multipurpose car. SW race cars sells AJE. They are basically designed for light weight No steering box and no torsion bars . AJE K-member is not the strongest
