BBP disc conversion on an early A

right on guys thank you! its crackedback that had the "dont believe the fmj spindle" hurrah. I read a few threads about it but it was people asking about using them on 67+ a's, i just couldnt find a solid answer for using them on early A's. so thanks gents, that answers most of my questions as to what balljoints to use. i will also be yanking the prop. valve out of this gran fury, and will convert mine to a dual pot master as well.
