Hey Craig, yes, my car is an original factory 400 with A/C. I have removed the A/C out of it since it was all jacked when I bought the car and also plan on going with the vintage air. But, to answer your question, my set up didnt have a spacer and was in fact sitting about half in and half out of the shroud. I did though add a spacer to mine, 1/2 spacer if I remember correctly, to push it in towards the radiator more and now it sits about 3/4 in and about a 1/4 out. Thats a guess and about where it sits, but could be slightly more in then 3/4. I was also having high temps and over heat problems last summer. I ended up having to replace the radiator cause it looked pretty bad and I put a alum 3 core in it and also replaced the pump with a Flow Kooler water pump and put in a 160 thermostat and now I run about 180 -190 on 90degree+ days with 80-90% humidity. I also had tried, before changing out the pump and radiator, using a 160, 180, and 190 degree thermostat and the car would still over heat. Also take a look at this post Water Pump Mod. This will also help if your water pump divider gap has never been adjusted.
