Go with the FMJ stuff, it will work fine.

I've done a bunch of cars with both A and FMJ stuff, none drove as through they were going to toss you off the road from bump steer.

One had about 50K miles on an FMJ swap when I sold it.

The scare mongers still exist from the article written in the 90's where IIRC, the author has said he'd never heard of a ball joint failure directly related to the additional spindle height. A friend ran the numbers and the additional angle at ball joint was 1.5* at both ends IIRC, 3* total through the swing. I'm pretty sure the ball joint tolerances were not built where an additional 1.5* was going to jam a stud to housing. This garbage is like a scary movie that isn't so scary...
