Check out Rockauto but also cross shop part numbers to find the best deal. I recommend the Gates brand. Any kit you get will most likely not have the water pump included you'll have to get that separate. I bought the gates water pump and it was identical to the stock one I pulled off.
This is the kit a I put on a local members SVT last month
Here are the water pumps as you can see they are identical.
Here is a pic when I did my timing belt in Ole' Yeller'. I bought the Gates Blue racing belt which I wouldn't recommend unless your doing a show car, it gets dirty rather quickly lol. Everything besides the t-belt was only 50 bucks if I remember right off of Rockauto 2-3 years ago when I bought everything. I had to piece together my own kit since I was using the blue belt and it doesn't come in a kit.
