I have a very hopped up merv I want to convert To a summit.

I know I need:
Exo cage
Body posts /mounts

What else do I really NEED to convert.
I know I need the driveshafts... but that's pricy for all 4 ends... and doesn't need to be upgraded...

I will be doing the springs.. so what springs should I get...?

Part numbers would be great. But looking to buy the parts Sunday. So help me out.
