Relocated leaf springs '69 Dart - Which shocks are correct?

Hi guys,

A friend is mounting in his '69 Dart a 440 Engine/5 speed transmission/Dana 60 and other goodies.
He had relocated the leaf springs, using Magnum Force relocating kit and springs.
Because the shock absorbers supports, attached in the leaf springs, are now shortening the absorbers course, we are trying to find the correct shocks.

Guys who had relocated the leaf springs, which kind of shocks are using in the rear?
And in front, which will be nice to use with this setup (big block engine, big torsion bars)?
It's time to buy the shocks, that's the reason why we are asking about.

thanks!
