Went with polished front drive from junky. Had issues with water pump hitting the DSE second gen camaro subframe. He took it back and I got one with out res and that worked out fine. Guy is awesome for support. Anyways its a nice piece. For water pump I did not like the brass ones that came with it and went with these....

Nice and clean look. For thermostat I got the billet specialties swivel and just got normal ls thermostat for it.
