Well, I'd say it's a little late for that, lol. But like you, I try to make as many old parts work for me as I can. My 1/2" MC swap went well. A used MC from a Vision off eBay ($16), I cleaned it all up, honed the cylinder a little, didn't replace any seals, and it pumped up leak-free in about 10 minutes. I wasn't getting any pressure at first and thought maybe it did need new seals, but then it built up. It's as I had hoped it would be - better "feel" and more progression than the stock 14mm unit, but not quite as much lever travel as an 11mm unit. Truth be told, I've grown used to the 11mm unit on the other bike and all the travel doesn't bother me much any more. I also "fixed" it, lol. Turns out a big part of the problem was the lever, it was bent. It wasn't bent out or up or down, it was bent straight. The gentle curve most levers have? This one didn't curve. So, I clamped it in a vice and gave it a couple good whacks with a big rubber mallet. Now it curves out as it should and doesn't pull in almost to the grip like it used to.
