That ad is for a 99+ I'd stay away. If you have a you-pull-it type yard, generally people leave the v6 mustangs alone because they are v6's. But the t5's are perfectly good for these swaps, so you can have good luck getting them for cheap. I got mine for 150 bucks off of a car with 120k miles. That's less than half what people want on craigslist. If you go that route, the easiest way to get the trans out is to first remove the upper intake manifold, fuel rails, and wiring harness from the v6. Then you can get to the top 2 trans bolts easy as pie. Otherwise you'll be cursing as you try to snake your 3ft extension train up to those bolts.
