very nice cross member fabrication ! i do have a question though. as you are using a poly mount [unless my old eyeballs are seeing something different], i noticed you are not using the "extra" top plat usually enclosed with such mounts. at least the ones i have seen [and the two i have in hand] have this plate that is supposed to be installed between the mount and transmission tail shaft. mine seem to have a slight gap between the poly section and the actual area where the bolts install. is my mount defective, or do i not need the plate ? i have wondered this for years. perhaps you [or others] can shed some insight on this, as i know GM mounts are used in many applications other than those they were designed for.
