Rear end kit?

[J48chevy]

Ok, my slow moving build is going into the next stage. Finished installing the mustang 2 front end. I now want to order a rear leaf kit to install. My question is, do they make a kit with the 3.25 u-bolts to install a explorer rear end? I really do not want to order a kit for $600+ after shipping and then have to also purchase all new brackets. All thoughts would be appreciated. Also, where have you ordered these rear kits from? I see a few places, TCI, CCP, etc and they all seem to be about the same pricing. Kits I am looking at come with drop springs, all brackets, shocks, and shock mount cross member. Thanks.
