I won't be able to get the AC working on my '73 Charger until next summer. Even then, I'm not sure if I even want AC as there's something special about driving around in this old car with the windows down. So, rather than keeping the compressor on the engine to route the belts, I was wondering if I could replace the AC water pump pulley with a non-AC water pump pulley with no additional changes? IE: keep the four groove crank pulley, the two groove alternator pulley, and all the brackets. This is the pulley I'm looking at buying: http://store.440source.com/Water-Pump-Pulley-Non-A_C-New-Reproduction/productinfo/132-1002/ Thanks!
