I got mine from Parkway Ford,
www.parkwayfordga.com They have the cheapest price that I could find so I went with them. The only problem that I had was that they didn't have the bolts, gaskets, and other miscellaneous things in stock. And they didn't bother telling us. So when we got the kit it wasn't complete so we had to scrounge up everything around here which delayed the install quite a bit. Only other thing was the alternator bracket didn't fit just right so they had to cut it. But besides that, the kit is complete and comes at a really good price. Have fun if you get it, it makes a big difference. The total price for the kit was a little over $1200, then $650 for the install. We know the guy who installed them so he gave us some slack in the price.
