Focus on the 2-3 mod: remove mid-seal in Dir pack, 2nd ring on Center-Support and block the Rev bleed at the sep-plate or more assuradly at the center support hole (1/4" plug).
2-3 accum: ONLY flip the VB piston and remove its spring. Case 2-3 puck-spring-pin remains stock. No pluggings. Some VB pucks need their 3-cast tabs ground flush to make like the 65-70 piston.
