First check to make sure you have the linkage going from the tranny to the firewall/steering column. If you change gears on the console and the column inside doesn't spin then you may be missing this linkage. If this is the case, check the parts for sale section and contact Terry Ritter, he can help you.
If the linkage is there and hooked up but the NSS doesn't engage then try using your hand to twist the column as far as it will go counter-clockwise and see if it will start; if it does then your linkage just needs to be adjusted to twist the column more.
After you've played with it a little more just let us know what the results are and we'll go from there.
