Hello Hal. I made my own engine mounts recently after the non Doomsday brand failed: https://photos.app.goo.gl/R821V51gw5v9gYsUA I can send measurements if you need, but I used an RC lower control arm from a 4" lift kit that wasn't used. I am in the middle of quite a few mods right now, including AC & serpentine. I added an auxiliary fuel tank, but still use the OE tank. All I did for the fuel inlet is remove the flapper valve so a diesel fuel filler will fit.
