global west still stocks the delerin frt upper and lower bushings. I did the rear heimjoint setup on the 415 a number of years ago. I also purchased the adjustable heim joint dog legs for the rear and the antiquated brackets from DRM. That combined with the cbeam plates and the coil overs from DRM made the car very predictable under hard acceleration and in tight turns on "Active Handling Runs" in the hills along the Mississippi River. Looking for the heim kits for the rear on the 93 now.
