I assume you are talking about the kits that are sold to install transmission side mounts for those who wish to use the stock front engine mount set-up. I use this side-mount set-up in my '57 chevy hardtop but note that this kit fastens to the stock frame "horns" where the old side-mounts connected to. I don't think this side mount kit will work in a truck, certainly the AD's, because the frames are completely different.
