Front end suspension kit

I ordered the full super Front End Kit for our 68 Dart from PST

Now I have a question cause I have not replaced these parts before on a Dodge all at one time...

My friend is helping me and he suggested that the Torsion Bars have to be taken out in order to replace the suspension parts.

I am baffled about this thinking that if anything just backing off the torsion and relaxing them would be enough...

Can you give me some advice on this subject..

This task will be performed on a nice host... so access is great

thanks in advance
