You don't have to buy anyone's kit to be able to put the rears up front, you just need longer shackles and get rid of the stock front bumper and space the front driveline. It is completely a simple bolt on with no drilling, welding, or any other mod!
Apparently you guys are forgetting how simple zukis are to build. Putting those springs on the front is easier than doing a spring over! You don't need to buy anything but a driveline spacer or an extended slip yoke for the front driveline. You don't need to relocate the spring hanger, or redrill the spring pads, or anything else!
I know, because I have done about a dozen of these swaps over the years. You only need to do any of the other stuff if you plan on using Jeep springs on the front, or you want to use the existing stock front bumper (WHY WOULD YOU WANT TO DO THAT??).
jUST DO THE MODS TO THE SPRINGS LIKE I say, and bolt them on and be happy with the results.
You nkow, DON'T WORRY, BE HAPPY! Hehe! Sorry, couldn't help myself...hehe.
