Denny @ HDK has been a huge help in cleaning up a AJE suspension kit I bought. I have a full tubed setup with steering rack, but its been plague with problems. The kit I have uses aluminum blocks to allow a forward facing tie rod location on the factory knuckles. There is a possibility of steering abnormalities which may require my purchasing a replacement k-member, lower control arms, and Mustang 2 spindles from HDK. Thats roughly another $2K on top of the almost $5k I have spent to get this far. So much of the kit I bought has been rebuilt or replaced, that I really shouldnt have bought the kit at all. The only thing I will have retained from the original purchase would be the rack... :-(
