I think any good A/C shop can easily do it. The tricky bit is under the gas tank, you will have to remove it. I would definitely get references. I have yet to find a good A/C shop, so I just bought the tools myself . (hose crimpers, etc, about $300). I hope you can find a shop to trust, it is all simple American fittings and hose. Don't let them convince you to switch to R-134, pay the extra for R12 like stock.
