When should you upgrade torsion bars?

Alright, so I ordered the 6 lead Espo’s with +1” and I ordered the 1.08” torsion bars from PST with new bushings and clips. My adjusters are free so I will reuse those. What else would you recommend to make the install of the springs and bars easier. I have hear Mancini has a good set of shackles, and i know I am going to need a new set of u bolts. Where do you guys order ubolts and bushings and crap like that? Lots to choose from and don’t want to have issues shortly after installing. Thanks for all the advice thus far and thanks for your responses!

Also, after I install everything I plan on heading down to my buddies fav shop to have some custom made sub frame connectors installed. Sadly enough I have to wait for the snow to melt...so it may be awhile...
