Don't convert it! I have a 80s Pinarello Dolomite that I love and wouldn't convert to fixed. Keep conversions limited to the japanese stuff! I did pretty much all the same reconditioning work that you'll have to do, and although it cost me a couple hundred for tools + parts, the end result was so worth it. Those Pinarello decals were crap, though, and mine are flaking off as well.
