"A" different spindle

Hi, I got the Mustang II, 2" dropped from Willwood. Top quality piece, includes bolt-on steering arm,(front/rear) steer? This was suppossedly co-developed with AME.(Morrison). I think, if enough people asked for a mod' to the bolt pattern on the bottom of spindle, to take the 73' up, "A" body lower ball joint/steering arm, we could all benefit. Meanwhile, I will probably "fudge" the difference,.5" total, and give it a fit. Thoughts? ateam.:cheers:
