This is a bit of older information, but still very worthwhile. I bought a bunch of parts from Jeg's a couple years ago when I was planning on going with a leaf spring ladder bar set up. Just under a year later, I decided to go with a g-bar set up instead. I thought I'd be out all the money for the parts, but thankfully I bought them from Jegs. I checked their return policy and they allow you to return stuff up to one year as long as it's still in the original box. I ended up returning about $3k worth of parts, no questions asked. Summit on the other hand, only allows 90 day returns. I know Summit and Jegs keep competing with prices, but if you're not completely sure, at least with Jegs you have a year to decide.
