Raising the front end 69 Cuda

You will lose all positive caster.

That was one of my concerns. But I did install offset bushings in the upper control arms because the big disc brakes and the large ball joint control arm made it impossible to align. The offset bushings solved the problem. I was wondering if they made tubular control arms that allow the suspension to rise without hitting the bump stop?? And if they were adjustable, wouldn't the alignment guy be able to solve the caster problem??But I don't know if anyone knows if it would allow me to raise the front by switching to another type of upper control arm??
I know somebody on FABO has solved this problem before....
