When beefing up the rear with an adjustable A/R bar, I'm aware of the after market drop link connector that attaches to the spring plates. There doesn't seem to be anyone that offered an adaptor to use the old ball attached to the trailing arms... for the early fixed type. I'm just wondering why?

A) alignment issue with the length of the arms on the adjustable A/R bar?

B) the strength of the ball connector on the trailing arm for the bigger A/R bars?

C) other issues?..... such a limited concern to most and well, just use the spring plates!

thanks,
