The components for pre and post 2K are all mostly the same, the only big difference is the threads for the pump guide rod and in some cases the velocity adjuster in the rear.
You would need:
- Body, back block, detent, vert asa, vert asa 12pt screw and o-ring
- Pump, gide rod, pump rod
- Internals: Valve and guide, Valve retaining screw, valve jam nut, hammer, velocity adjuster, cocking rod, plus springs and O-rings
- You also need a frame and maybe a beaver tail
- also a bolt
Hope this helps
