Get a custom k-member with coil overs and a rack&pinion . You'll have the extra room and the handling. For a good suspension with no install issues I would contact. HDK HemiDenny on this site. By far the best fitting with no issues from every one that bought from him.
I bought an AJE in a project car thinking I was getting a good deal. It was a disaster getting the components to make it work. Most of the parts we had to modify. spindles didn't fit the uppers plus other issues. We have a fab shop so we were able to do the corrections . If you don't have the equipment to correct things beware and do your homework
My friend just bought a popular suspension. I won't say from who but nothing fit smooth and any QQuestions or help from AA person they didn't have one one answer. He just came here to have the mounts modified to fit after the second set. Some of the mount holes were 3/8 when they should have been 7/16. They told him just use the smaller bolts they'll fit the block . Make sure there are tight They said.
