Im very happy with mine so far. Im just getting to sealing up all the holes in the firewall. The steering shaft hole is wide open (moved over for v8) the brake pedal hole and new hole (moved over for v8) is wide open inches from the exhaust manifold. There are probably 10 open holes all together plus the heater core is still flowing and that underdash unit is still pumping out cold air. Im sure once i seal it up and put the floor insulation and mat in the cab it will be way better. Not to mention the roof with no insulation or headliner. Its just a pice of hot tin over your head. Im guessing once I improve all those things its going to just keep getting better and better.
