[Fot] TR3 to TR4A ball joint issue

[davehogye]

Hello all, 
I've noticed after installing TR4A upper control arms and ball joints on my TR3, that the suspension no longer rests on the bumpers below the spring pan. The ball joints do not allow full extension. I purchased the ball joints from The Roadster Factory. I'm wondering if another suppliers ball joints might allow more movement. It sure doesn't seem good to me that the suspension at full extension should rest against the ball joint. I guess that a taller bumper could be used. Any tips or info on this matter would be appreciated. 
Thanks, 
Dave H.
