subframe connectors

Make your own, but I never installed them in my old '67 Dart GT hardtop. The car never felt like it flexed. It had a stock 440 backed by an 18-spline four speed and 3.23SG 8-34 with NO traction aids. When we put that drive train in my son's '67 convertible we put the connectors in before the drive train. I have seen the results of body flex in my 340 GTS convertible, which will not get connectors due to its rarity. My Barracuda convertible also got connectors prior to engine install (440/727).
