Does anybody know of any more good 4 link kits for the 1st series AD trucks? The rear end will be a 9inch f***,

. That word is forbidden word in a Chevy forum correct? LOL

I found one on
Heidt's Website for $1,085 and one on
Brother's Website for $1,296. The one on brother's includes the panhard bar and coil over shocks that will be replaced with air bags so I feel it's the better deal. Has anybody used either one of these kits?
