I use the mini-spool from Trail Tough. Works great and I've never had a problem with it.
There was a white Tracker on here that used a universal roof rack, but it was a four door. With the 2 door, unless it's a hard top, you need to either build a custom mount off or look at buying the Calimini kit.
For the winch, I would keep an eye out on Craigslist. If you don't mind it being a little slow, you can usually pick up Chicago Electric or other similar winches for pretty cheap with bad motors, then just order a new motor. Just remember to take the winch motor off once a year to clean it up, as dust gets into the engines, then they get wet, turns to mud, then the magnets break off.

The Garage Sale section is great for finding deals from fellow Zuki members. Just depends on what your looking for!
